1 million Twitter users
On January 6, 2008, I predicted that Twitter would reach 1 million public uers before April 1, 2008. Twitdir reports the number of public Twitter users it has detected. Around mid February it seemed that the Twitter user base was growing faster than I expected. In the beginning of March however the growth slowed down. This reduced growth has continued until now, see the graph below.
If this reduced growth continues at the same speed, the 1 million mark of public Twitter users according to Twitdir will be reached only around June 2008. There is no explanation why the growth of the Twitter user base suddenly changed from 3,500 new users per day to 750 new users per day.
As mentioned in one of the previous posts on this blog, the number of private Twitter users could be around 15%. This implies that the total number of Twitter accounts at this very moment already exceeds 1 million.

I don't know how twitdir calculates it's results, but twitterholic significantly disagrees, it thinks there are already a lot more than 12 million accounts on twitter
This is someone who signed up 3 months ago but twitterholic reports "timothysykes was the 11,247,222th person to sign up for twitter!"
The sudden and fixed drop in signups per day on twitdir suggests to me it's statistics are just broken from start to finish.
Hello ewan,
please have a look at a follow up post : Twitter id's and number of Twitter users
There is definitely a systematic error in there. There must be a reason which is unrelated to actual user numbers which causes the incontinuity. By systematic error I mean a change in measuring users, an internal Twitter reconfiguration, a logs reset etc. I'm not doubting how many the users are at the moment - just how they got there.
