According to their research, 90% of Twitter's content is generated only by 10% of its users. Most users only "tweet" once in their lifetime, and half only update their page once every 74 days. Graduate Bill Heil who took part in the work, comments that, "Based on the numbers, Twitter is certainly not a service where everyone has seen it has instantly loved it." The team also note that "This implies that Twitter's resembles more of a one-way, one-to-many publishing service more than a two-way, peer-to-peer communication network". Other interesting data from the study revealed that "men have 15% more followers than women", "an average man is almost twice more likely to follow another man than a woman", and "An average woman is 25% more likely to follow a man than a woman." This is interesting because they claim that, on typical online social networks, "most of the activity is focused around women"."
