While it stil exists as part of Mercury I ended up abandoning the old code I had for facebook connect.  It worked fine for logins and some basic stuff but the new APIs that Facebook has were not playing well with it.  It's been a frustrating process but I have rewritten the Facebook Connect login code in Mercury and have also extended the functionality with the ability to post on the Facebook wall without additional prompting, given a validated account.

I have yet to stitch it into the blog module and I don't know that I'll have time to do that tonight.  But once I do blog posts can automatically be broadcast to both Twitter and Facebook!
