• New Twitter Research: Men Follow Men and Nobody Tweets – Conversation Starter – HarvardBusiness.org – "Although men and women follow a similar number of Twitter users, men have 15% more followers than women. Men also have more reciprocated relationships, in which two users follow each other. This "follower split" suggests that women are driven less by followers than men, or have more stringent thresholds for reciprocating relationships. This is intriguing, especially given that females hold a slight majority on Twitter: we found that men comprise 45% of Twitter users, while women represent 55%."
• Shirky: Power Laws, Weblogs, and Inequality – 2003 article on popularity / traffic on blogs, which was then the latest emerging social media format. "Once a power law distribution exists, it can take on a certain amount of homeostasis, the tendency of a system to retain its form even against external pressures. Is the weblog world such a system? Are there people who are as talented or deserving as the current stars, but who are not getting anything like the traffic? Doubtless. Will this problem get worse in the future? Yes. "
