My biggest issue with Facebook is that it is so incredibly buggy. It seems like they don't run any testing before doing changes to the UI or releasing new features. Basic functionality seems to only be working off-and-on, and sometimes you just get periods where Facebook becomes totally unusable, for instance when your news feed (or "News Ahoy!" as it says on mine) is sorted completely randomly and only shows old updates (and no, I'm not talking about the "Shiniest booty" here, but the "Fresh booty").

Yes, I use Pirate as the language on Facebook, can you tell?
