Facebook revisited

I have now been on Facebook for about a week, and I can see how people spend so much time online. There is so much to do and update, but I have overcome my feeling of 'information overload' now that I am used to the display. I have learned how to add a link to a YouTube video, upload photos and create albums, as well as using tagging to label people in my photos. I think that Facebook is a good resource for social networking of a personal nature, but I took a quick look at LinkedIn and it seems to be more effective at professional networking. Facebook is far more informal and has more details about people's personal lives, interests and hobbies (e.g. becoming a fan of celebrities, sharing holiday photos, etc); whereas, LinkedIn is focused on professional identity and making new contacts.
