50% of Twitter content is created by less than 1% of service users.

I don’t know how successful this headline is, but it conveys the meaning of the news quite accurately - there are very few users in the Twitter microblogging service who actually generate content. Experts say that less than 1% of Twitter users of the total number (190 million people) produce more than half of all content on the service. You will be surprised, but “less than 1%” is only 0.05% of users. Thus, out of all these hundreds of millions, 20 thousand people actively communicate and create content.

At the same time, top bloggers like Charlie Sheen (top - in the sense, with the maximum number of followers) have nothing to do with this share of “useful for society” users. The most "productive" Twittermen are journalists, bloggers, authors, who are called in the study "elite" members of the community. Probably the same situation is observed on many services, but still such a small number of active users cannot but surprise. By the way, research on Twitter was conducted by experts from Cornell University and Yahoo Research.

In their report, experts also say that very few top bloggers on Twitter communicate with regular bloggers: “celebrities listen to celebrities, bloggers listen to bloggers”. And bloggers, according to analysts, are representatives of the most influential group in the service, because they produce the lion’s share of content on Twitter.

Research, experts say, helps to better understand how people communicate using modern services. Twitter itself, according to the initiators of the study, is more like a center for sharing information between communities and individual users - in this respect there are quite a few differences between social networks and Twitter, which is also considered a social network.
