3 million Twitter users

On June 29, 2008 I wrote on this blog that Twitter reached 2 million users - according to Twitdir. Twitter has passed another milestone a few days ago, 3 million users. As Twitdir only "knows" Twitter users with a public profile, the actual number of Twitter users is higher, as discussed in this blogpost.


The growth of Twitter users follows an exponential curve - at least until now. If the same trend continues, 4 million will be reached around mid November. Around Christmas the 5 million mark will be reached. 6 million will be reached around mid January 2009 and 7 million around Mid February. Whatever the trend will be, I will continue to monitor this trend.
