Just to make things even more confusing, Kara Swisher at All Things D got two very different statements from Steve Jobs and Phil Schiller at the event yesterday: Schiller was enthusiastic about finding friends via Facebook, while Jobs said Zuckerberg and co. were demanding "onerous terms" that Apple refused. We're assuming Jobs was talking about something deeper than just finding friends via Connect, but it's still all very strange -- and as it stands, finding friends on Ping right now requires a fair bit of guesswork and searching, so we're hoping this all gets sorted soon. Check the video of Phil Schiller talking about Facebook and Ping after the break, as well as a snap of it (sort of) working from last night.
Update: We can't confirm this, but we've just gotten a tip saying the problem is primarily on Facebook's end -- the service is currently denying requests from Ping, and the resulting errors apparently caused enough other problems for Apple to pull the plug on the connection entirely until it's fixed. That certainly would explain why Ping has seemed buggy and slow from the outset, but we're still waiting for some official explanation of what's going on.
