Oh, the burdens of popularity. We already know that most people on Twitter are sheep with few followers and who don't Tweet much. But what about the rams? If you want to lead a flock on Twitter, you need to be heard. People with 100 followers send out an average of 2.4 Tweets per day, while those with 1,800 followers Tweet an average of 10.2 a day, according to a new study by Sysomos , a social media analytics company based in Toronto. The inflection point seems to be between 800 followers (2.8 Tweets a day) and 1,000 followers (6.4 Tweets a day). The more followers you have, the more you Tweet. Perhaps once people attract a large enough audience they feel obligated to keep them entertained. More likely, the more you Tweet the more followers you get, provided you actually have something interesting to say. As it turns out, not everybody uses Twitter as a broadcast mechanism. Many people simply tune in passively and skim their feeds. Sysomos looked at 11.5 million Twitter accounts and concluded that the top 10 percent of Twitter users produce 86 percent of the Tweets (which closely matches a Harvard Business School study that estimates the top 10 percent of Twitter users do 90 percent of the Tweeting). It is even more concentrated than that. The Sysomos data indicates that the top 5 percent of people on Twitter account for 75 percent of all Tweets.
