Twitter.com response time

I just did a couple of tests with host-tracker to get an idea of the response times of the Twitter website.



Test 1
Received responses : 37
Average response time : 1.93 sec

Test 2
Received responses: 34
Average response time: 1.92 sec

Test 3
Received responses: 35
Average response time: 1.09

Test 4
Received responses: 36
Average response time: 1.17

I have the impression that when I launch Twitter.com myself, it takes more time to load.

Unfortunately the uptime statistics for Twitter.com at pingdom have stopped working from August 7, 2007.

Does anyone else know others tools monitoring the availability or response times of Twitter.com ?

Followers, Friends, Fans, Admirers, Connections, Subscribers, Visitors, ...

My Twitter account has several followers, and I am following also several Twitter accounts. I have a lot of friends on Facebook. I have a few fans on Pownce. I have admirers on MyBlogLog. I have connections on Linkedin. Several persons are subscribers to the feeds of my blogs on Bloglines. The OneStat counter records the visitors of this blog.

Luckily, I have still friends for which I do not need fancy tools to meet and to have fun.

Twitstat

Twitstat.com is an initiative of Michiel Berger from The Netherlands. He was looking for a nice tool to follow the Twitosphere. If you have been away for a couple of days, the Twitter interface does not allow you to quickly spot the most interesting topics being discussed within the community of your Twitter followers. He developed Twitstat.com as his own solution.

Twitstat monitors the Twitter messages from the users following the Twitstat account on Twitter. On Twitstat.com the detailed list of Twitter messages from the followers of Twitstat account on Twitter is shown. Twitstat.com also shows an overview by day of the total number of Twitter messages indexed and the top 10 of most active Twitter users for today and yesterday. Launched only on August 22, 2007, Twitstat is live for a couple of weeks. Currently the Twitstat account on Twitter is being followed by 96 other Twitter accounts, mostly from The Netherlands. The previous days around 800 Twitter messages have been indexed daily.


Twitstat also offers the possiblity to obtain statistics for an individual Twitter user. The picture below shows an overview of the Twitter messages from Erwin Blom, one of the most active Twitter users in The Netherlands (see also the Second state of the Dutch Twitosphere).


Another interesting feature of Twitstat is the possiblity to see how often and when a search string was present in the indexed Twitter messages. The picture below shows all Twitter messages containing the word "Twitter".


The graphs shown by Twitstat can be improved. Only the left most and right most columns are labeled with a date. The current graphs only contain columns for dates with Twitter messages, dates without messages are not shown as data points on the graph. The graphs are not a correct display of the time distribution of the indexed Twitter messages. For an example, have a look at the graph for search string "pownce". There were messages on 30-08-2007, 05-09-2007, 09-09-2007 and 11-09-2007. The graphs contains 4 columns, only two of them are labeled.


A very nice thing of Twitstat.com is that everything is also available as an RSS-feed. You can even get an RSS feed to find Twitter messages from a given Twitter user and a given search string. This RSS feed gives all Twitter messages from Marketingfacts containing "tinyurl".

Currently, Twitstat.com isn't even in beta yet. The number of Twitter accounts followed is rather limited. The response times of Twitstat are amazingly fast. Will this be also the case if Twitstat becomes more popular ? I can imagine that keeping Twitstat alive will require some funding (e.g. for the storage of data or the bandwith) in the future. Will Twitstat.com remain ad-free ?

If Twitstat.com becomes too popular there is a risk that its usefulness will decrease. I can imagine a situation in which a Twitter user from The Netherlands is interested in a specific topic discussed within the Dutch Twitter community. If this topic is also discussed in the global Twitophsere (indexed by Twitstat) the search results for the specific topic will probably contain a lot of Twitter messages in which the Twitter user is not interested in. The signal to noice ratio will decrease.

Private Twitter accounts visible on Facebook

Messages from private Twitter accounts should be only read by other Twitter accounts that have been approved by the owner of the private Twitter account. I discovered that messages from private Twitter accounts can be read by other users on Facebook.

Peter Dedecker is one of my friends on Facebook. I am however not a follower of his private Twitter account. With my Twitter account I do not have access to his private Twitter messages.



Peter installed the Twitter application on Facebook, showing his Twitter messages on his Facebook account.



If you have a private Twitter account you have to be careful by installing the Twitter application on Facebook. This application assumes that all your friend on Facebook have also been accepted to follow your private messages on Twitter.

Update September 14, 2007
According to this blogpost new Twitter accounts cannot be accessed anymore thru Facebook. I just checked if I still have access to the private Twitter account used in the original post, which is still the case. It seems that private Twitters accounts that already are linked to Facebook accounts remain visible.

Twitter People Search

This week profile search was added to Twitter, as announced on Twitter and on the Twitter blog.

Earlier this week, Terraminds, a brand new Twitter search engine was announced, also on Twitter and on a blog. Terraminds allows to search in updates and also in users.

The arrival of these two brand new Twitter people search tools is a good opportunity to review three Twitter people search engines.

Twitter search


Launched : August 22, 2007

Grouping : Results in groups of 20
Search space : account name, name, web, location and bio
Search arguments : Full matching of search string : "travel" will not return "traveler", multiple terms accepted "John Mexico" will return all Twitter users where "John" appears in one of the fields and where "Mexico" also appears in one the fields, not necessary the same field containing "John"
Response times : very fast
Additional information : in operation only for a few days, number of known Twitter users is probably still rather limited
A few test cases :

Travel : about 75 twitter users who posted in the last 1 week
Linkedin : about 1 twitter users who posted in the last 1 week


There are also search tools capable of searching for Twitter messages. See my previous post on this subject. Indirectly these tools allow also to look up Twitter users based on search arguments appearing in their messages.

Is there still a future for Twitter people search tools now that Twitter has launched profile search ? I personally think there is still room for Twitter people search tools offering something more. What is currently lacking is advanced search. None of the search tools accept complex query syntax with operators as "and", "or" and "not". Futhermore, currently all fields are searched. It is not possible to limit a search to a specific field, e.g. only Twitter with miami as location.

Virtual travel agent on Twitter

Marco Derksen, owner of Marketingfacts.nl, the most famous marketing blog in The Netherlands, just spent his holiday in Finland. What has this to do with Twitter ? Quite a lot.

When Marco was thinking of finding a holiday location, he asked advice to his 300+ followers on Twitter. He got several suggestions, including Finland. When he later asked for specific tips for Finland, he received several of them. When he finally made it to Finland, he stayed in touch with his homebase by informing his followers of his wherabouts and his travel experiences in Finland.

Upon his return, he made a blogpost and a presentation (both in Dutch) describing his experiences. He suggests another, innovative use of Twitter, Twitter as a virtual Travel Agent. He already started several new Twitter accounts for people traveling to various holiday locations (Amsterdam, United States, Australia, Canada and Finland). The goal is that someone, e.g.John Smith planning to go to one of these holiday locations, would follow the Twitter account for his destination. The Twitter travel account will also follow John Smith's Twitter account. When John Smith would ask questions in his Twitter feed, these answers will be picked up by the location experts for the Twitter account. Ideally tourists would also exchange travel tips between themselves. If there would be an interface between Twitter and a photo sharing service (e.g. Flickr), tourists and location experts can also exchange pictures. The advantage for John Smith of using Twitter during hist stay at the holiday location, is that he can receive travel tips on his mobile phone.

Marco's suggestion to use Twitter as a virtual travel agent has however also its limitations. This worked fine for Marco, because of his impressive network (on Twitter but also through the Marketingfacts blog and in real life in the Netherlands). What is lacking from his idea is the funding. Why would someone help people he never met before (and probably will never meet) with travel tips for a location ? Who will pay the location experts ? There are plenty of other sites where you can find useful information during the planning phase of a holiday. Twitter is OK for exchange of messages, but it is rather difficult to look up Twitter messages from the past.

Future will tell if Twitter will be used as a virtual travel agent.

Second state of the DutchTwitosphere

On April 22, 2007 I published the first state of the Twitosphere in the Netherlands. With this new state of the Twitosphere I want to give an idea how the Twitosphere in the Netherlands has evolved from then.

Using the same approach as for the first state of the Twitosphere, I managed to find 2090 active Twitter accounts from the Netherlands. A Twitter account was considered to be held by someone from the Netherlands if the location explicitely refers to the Netherlands or if the Twitter user was located in the Netherlands according to one of the Twitter mapping mashups. The actual number of Twitter users in the Netherlands is probably higher as only 50% of the Twitter users specify their location in their profile (see this previous post).

For a population of 16.57 million people (according to Wikipedia), the Netherlands has 2090 Twitter accounts, which means that there is a Twitter account for every 7,928 inhabitants.

History of the Twitter accounts in the Netherlands
This graph below shows the history of the Twitter accounts in the Netherlands. The graph is based on the date of the first message posted on each of the public Twitter accounts. For private Twitter accounts (177) the date of the first message is not accessible. In addition to that, there are still 88 Twitter accounts without a single update, they are still waiting for the first message to be published. The growth of the number of Twitter accounts in the Netherlands accelerated from mid March 2007. This accelerated growth seems to continue until now. On an average day 8 new Twitter accounts are created by someone from the Netherlands.



Degree of activity
The graph below is generated only for the Twitter accounts where I could determine the date of the first message and the date of the last message, meaning that Twitter users without messages and private Twitter accounts were left out.

The graph contains two parts. In the upper part, Twitter users who have published at one Twitter message in the last 14 days are plotted as a line, starting from the date of the first message to the date of the last message. The color of the line depends on the number of messages (also called updates) published. The lower part contains Twitters users without updates in the last 14 dates. These accounts can perhaps be considered as inactive accounts.

The lines in the lower part of the graph are much shorter and show almost no colors.


Types of Twitters users in the Netherlands
A while ago I published a blogpost describing 4 types of Twitter users : Lurkers, Bots, High Influentials and Twitter stars.

On the graph below all 2090 Twitter users in the Netherlands are plotted according to their number of updates and the number of followers. There are currently no High Influential Twitter users (high number of followers but low number of updates). There are several Bots - Twitter accounts where the messages are automatically generated (low number of followers and very high number of updates). Luckily there are several Twitter Stars in the Netherlands, e.g. twitter.com/Dutchcowboy, twitter.com/erwblo, twitter.com/frankmeeuwsen, twitter.com/gervis, twitter.com/marketingfacts en twitter.com/tonie.



Top lists
To conclude this state of the Twitosphere, several top lists of Twitter accounts according to different criteria.

Second state of the Belgian Twitosphere

On April 17, 2007 I published the first state of the Twitosphere in Belgium, my home country. With this new state of the Twitosphere I want to give an idea how the Belgium Twitosphere has evolved since then.

Using the same approach as for the first state of the Twitosphere, I managed to find 854 active Twitter accounts from Belgium. A Twitter account was considered to be held by someone from Belgium if the location explicitely refers to Belgium or if the Twitter user was located in Belgium according to one of the Twitter mapping mashups. The actual number of Belgian Twitter users is probably higher as only 50% of the Twitter users specify their location in their profile (see this previous post).

For a population of 10.5 million people (according to Wikipedia), Belgium has 854 Twitter accounts, which means that there is a Twitter account for every 12,295 inhabitants.

History of the Belgian Twitter accounts
This graph below shows the history of the Belgian Twitter accounts. The graph is based on the date of the first message posted on each of the public Belgian Twitter accounts. For the 107 private Twitter accounts the date of the first message is not accessible. In addition to that, there are still 25 Belgian Twitter accounts without a single update, they are still waiting for the first message to be published. This leads to a graph based on 693 Twitter accounts. The growth of the number of Twitter accounts in Belgium accelerated from mid March 2007. This accelerated growth seems to continue until now.


Degree of activity
The graph below is generated only for the Twitter accounts where I could determine the date of the first message and the date of the last message, meaning that Twitter users without messages and private Twitter accounts were left out.

These accounts can perhaps be considered as inactive accounts.

The lines in the lower part of the graph are much shorter and show almost no colors, confirming the hypothesis that these Twitter accounts are inactive.

First state of the Twitosphere in Brazil

I published already several blogposts on this blog with an analysis of the Twitosphere is several European countries (see the sidebar). The next country analyzed is not in Europe this time, but in South America : Brazil.

Using the same approach as for the previous countries, I managed to find 421 active Twitter accounts from Brazil. A Twitter account was considered to be held by someone from Brazil if the location explicitely refers to Brazil or if the Twitter user was located in Brazil according to one of the Twitter mapping mashups. The actual number of Brazilian Twitter users is probably higher as only 50% of the Twitter users specify their location in their profile (see this previous post).

For a population of 190 million people (according to Wikipedia), Brazil has 421 Twitter accounts, which means that there is a Brazilian Twitter account for every 451,000 inhabitants. Currently for Iceland and the Netherlands there is one Twitter account for roughly 10,000 inhabitants.

History of the Brazilian Twitter accounts
This graph below shows the history of the Brazilian Twitter accounts. The graph is based on the date of the first message posted on each of the public Brazilian Twitter accounts.

Public of Private
Only 36 Twitter acounts from Brazil or 8.6% have chosen to keep their updates only available to their friends. In the analyzed European countries this percentage varied from 3.5% (Italy) to 22% (Belgium).

Number of following
A Twitter user can choose to follow one or more other Twitter accounts, called "following". 10% of the Brazilian Twitter accounts do not follow other Twitter users. An average Twitter account from Brazil follows 12,0 Twitter accounts. In the analyzed European countries this average varied from 9,6 (Belgium) to 32 (Italy).

Number of followers
A follower is someone who has indicated another Twitter account as following and receives all updates of that other Twitter account. 6% of the accounts have no Twitter followers at all, meaning that no one else on Twitter has indicated this account as following. An average Twitter account from Brazil has 12.0 followers. This average is in line with the averages observed for the European countries : between 10.5 (Belgium) to 26 (Italy).

Updates
Only 3% of the accounts from Brazil are still waiting for their first update to be published. Currently an average Twitter account from Brazil has 57 updates, which is lower than the averages observed for the European countries from 72 (Belgium) to 106 (Italy and Spain). The lower average for Brazil can be explained by the fact that there is only one Twitter account with automatically generated Twitter messages. This kind of Twitter messages are often generated by news services. Please keep in mind that these averages are only snapshots, as lots of new Twitter messages (or Tweets) are published every day.

http://twitter.com/fernandolins - Fernando Lins - 658 updates
http://twitter.com/jplages - Joao Paulo - 516 updates
http://twitter.com/julielondongirl - ~*Julie*~ - 492 updates

Degree of activity
35% of all Twitter accounts from Brazil with a public feed did not post an update in the last 20 days. They can perhaps be considered as inactive accounts.

52% of all Twitter accounts from Brazil with a public feed did post at least one message in the last 7 days, indicating that these accounts are still alive. This percentage (52%) is significantly higher than the percentages of active users observed for the European countries.

Conclusion
This state of the Brazilian Twitosphere is only a snapshot, meaning that the figures mentioned in this post have already changed because the Twitosphere is a very dynamic environment with several new accounts being created every day, new connections being made between accounts (following/followers) and of course new messages being written every hour of the day.

Users from Brazil were among the first to start using Twitter (from July 2006). There was a sharp increase in the number of Twitter users in Brazil from mid April 2007, about at the same time as for the analyzed European countries. The main difference is that the growth continues for Brazil, whereas the growth slowed down for the European countries. The creation of new Twitter accounts in Brazil seems even to accelerate from the beginning of August 2007.

The current Twitter community in Brazil is increasing day by day, the percentage of active Twitter accounts is higher than in the analyzed European countries. The future for Twitter in Brazil looks bright.

Twitter shares

Twitter is (not yet) listed on an official stockmarket. Virtual shares of Twitter are however already at two fantasy stockmarkets. Let's have a at the current values of the Twitter shares.

On Urladex, the number of hits per million users according to Alexa determines the potential price of the site's share. The screenshot below shows the info from Urladex for Twitter.com, including a graph from Alexa showing the daily reach for the last three months.

The current share price for Twitter.com on Urladex is $1,475.



Trendio is a stock exchange where words from the news are the stocks. The value of the words is calculated according to their presence in the media.

The current share price for Twitter.com on Trendio is $4.72, with an all time high of $10,30 and an all time low of 3.53.



Is there someone who has an idea of the value of the real Twitter shares ?
