Social Network Site Use

Social network sites are of great interest to researchers. Usage statistics are quite difficult to find, as these sites grow so quickly. Additionally, the difficulty in measuring "use" include defining heavy versus light use as well as determining real profiles versus fake profiles and multiple profiles. Blogger and research analyst Jeremiah Owyang has compiled a list of usage data for many popular sites and says that he will continue to update this page. This will be an excellent reference for anyone interested in social network sites.
