Early 2007 was before Facebook Apps came out. There was no Farmville, no SuperPoke, no Scrabulous, no Washington Post Social Reader. It was also before Facebook Status Messages (IIRC a reaction to Twitter, which hadn't gained traction yet), before the News Feed (IIRC a reaction to Friendfeed, which wouldn't be founded for another few months), before the Facebook Mobile App (the iPhone was brand new and didn't yet allow 3rd-party apps, Android hadn't come out yet), and the UI was completely different. There was no Facebook Connect or Like button.
