Recently, their XMPP server silently began assigning authenticating
users strings of random digits (e.g. 0329802437509@xxxxxxxxxxxx,
approximately) as usernames. I remember a core Pidgin dev with a lot of
protocol experience saying that accepting this response is either unsafe
or a protocol violation (maybe both). However, most clients do, and
therefore still work with Facebook.

Regardless, having a username like that isn't very usable. I think there
are new issues with fetching buddy lists, too.
