Admirers of single sentences are many it seems, as Twitter announced that it passed the figure of 100 million active users.

Twitter’s CEO Dick Costolo said that the site has recorded an 82 percent increase in active users in 2011, i.e. users who log on at least once a month. On the other hand, half of the 100 million users apparently log on at least once a day.

Costolo said that he remains committed to keeping Twitter independent and said that he has no plans to make the company public. However, he conceded the site is ready to expand and added that it will broaden services where adverts appear. Namely, he spoke of promoted tweets, which would only appear if a user followed the company earlier.
