Did you know you can important blogs onto facebook? I'm going to open myself up to all kinds of fun discussions, I can tell.
Also, did you know people might be looking at your profile and you don't know it?
Please, for the love - check your privacy settings. This is one reason I like facebook a lot more than myspace. Don't like those news feeds you get? change it. Don't want people seeing what you do? change it.
Don't like seeing Jack's notes pop up in your news feed? change it ;)
