Dorcas Recently, logging in to facebook has become an obligation rather than a form of socialization.

Mark Dain Facebook has such a strong network effect it's hard to avoid it's existence. I'm not sure if that's because it's so big or because it's Facebook. I still enjoy coming to Sublevel though so at least there's that

Dorcas Absolutely. It became so big that it just Facebook itself. Same here. + points for Sublevel!
