I don't know what everyone's talking about... I love Facebook.
think about how out of the loop everyone would be if we didn't have Facebook/other social networking sites... it's by far the best way to keep in touch with your friends, find out what people are doing, and just discover things that you would otherwise be completely clueless about.
sure, they might make some weird layout changes/new features every now and then, but overall, I'm incredibly satisfied with it, and I will continue using it until it dies out (which might not be for a long time).
