I only use fb to communicate with friends, find friends, and play an occasional game app or two. But those reasons in the link, especially number 5, really get my thinking. Now that I know that fb "owns" my info, it makes me feel uncomfortable. I wouldn't want anyone having all my information, even my friends because anything can happen. Still, I don't use it much so it's not that much of a concern but still it's a bit worrying.
