Ahh OK, i gotcha. I really don't post much on Facebook, the last "status" update I posted was back in January after the Michigan bowl game. Before that it was in September. As for information, I don't have much on there, probably the same stuff, if not less, than I have on my profile here.
The people I cant stand on there are the ones who put their whole lives on Facebook. Let me know when you get a promotion, or are expecting a child, or getting married, major things like that. I don't need to hear/read that you just got done vacuuming or are eating a sandwich. I "hide" people who post to much junk, and I block all of the games that people post on there.
It really is what you want to make it out to be, you can post as much or as little as you want, limit the people who can see your profile and updates, hide or block people and apps. Like I said, I just use it to communicate with friends and family around the country. If you use it right, it's really not that bad.
Good luck if you decide to try it out.
