Some of you just do NOT seem to be able to get past your hatred of all things Facebook. And I suppose that's fine, but at some point there's going to have to be a Bitcoin presence on Facebook. There's no other good way to reach that crowd, and that crowd are the ones who Bitcoin is ultimately going to have to bring on board if the currency is to be successful.
The Facebook userbase != the Facebook platform. Creating a presence on Facebook is far far different than allowing Facebook to auth every connection to your highly secure bitcoin trading/retail/information site.
