Facebook

Clearly Facebook is more than a virtual social network. One can use the top 10 apps , not to mention the other 1990, to integrate his information needs and just live in Faceworld. Quick information, book clubs, bookmarks, reference, research-- the user never has to leave the site (except maybe to sleep). Personally, I'm not about to put my face forward, but I can see how those who are already in the Facebook groove would enjoy using these apps and save time normally "wasted" aka "logged out".
