RANT 1 - Facebook Cliques - What Facebook needs to make it better is what high school suck; Facebook needs cliques. You should be able to set up cliques in FB and the assign your contacts to one or more of them. Only people in a clique can see what the other clique members post, tag, etc about you. That way your mom doesn't get informed about the drunken video that Crazy Mike posted about the two of you last weekend.
RANT 2 - Facebook Diamonds - Imagine 4 people sitting around a table. Everyone knows the person to their left and right, but no one knows the person across from them. I've got 3 Facebook diamonds that I know of. Sass is in one. MelO is in another. The third is two non-blogger friends. (Yes, I have non-blogger friends on FB, smart-ashes!) It just kind of messes with you when your worlds collide. I'm looking at the people Facebook thinks I may know (and it thinks I should know everyone that Gwen and H have in common which is like 300 people) and it says, you and "Cindy Seafoam" have two friends in common. So you look at your mutual friends, and one is Sass and one is a girl you know from college.
It's like, WORLDS COLLIDING!
