Facebook: A Profile of Friends
Facebook: A Profile of its 'Friends, is composed of data highlights from the last few years of research done at the Pew Internet & American Life Project. "The project has been surveying people who use social media to explore how they use it and what they get out of it. Highlights from the surveys paint a portrait of what kind of people use sites such as Facebook, who they connect to and how they manage their privacy." As you read down through the featured points (such as "80% of Facebook user requests are accepted") you can click on the link to the rest of the report. There appear to be five "feeder" reports to this profile.
