It's amazing to me how much it's changed in so short a time. Remember when you didn't "friend" someone, you "added" them? Remember SuperPoke? Remember the "20 Things About Me" note trend? Remember notes, period? Remember when people used to get confused and write on their own walls? Remember when the mini-feed was new? Remember when your status always had an "is" in front of it? More mind-blowing than anything: remember when you didn't have Facebook?
