Sadly the twitter exodus seems to be coming to an end. From the peak of 1,333 users per day we are now back down to 322. Before the exodus we were seeing about 100 to 200 new users a day.
@freemo I think a slower growth is better. Since now people have started migrating in communities however I believe the amount of new users will increase in the future as more and more people belonging to those communities will get to know about it.
