If you follow me on Twitter or Facebook you already got a trio of screen grabs from my iPod on various things I have been working on today. With some help from Chris Hall at Six Apart and Dan Wolfgang (thanks for the suggestions guys) I was able to get further than before.
Dan pointed me to a better, newer, Userpic Template Module. Mine was pre-4.21 I guess. This solved the problem of bringing in Facebook profile pictures and MT native Userpics.
I am also going to theorize that it may take a couple days for Facebook to recognize a new app and the web site(s) that interact with that app, so thay may well be the reason for all those errors before.
I still get errors, two jQuery errors, but this is far better than what I saw previously. As you can see from the screen grab above, the round trip connection from BG Views to Facebook is working. My Facebook App is now syncing the comments, which it was not doing yesterday. Now it works, and looks like this:

There is a bug report in by Chris about the jQuery issues. I hope they get it straitened out soon. If you are wondering "but Ken, what does it break?" It prevents a couple things:
- The Sign In | Register does not show up in the upper right of any article page.
- The Name, Email and (depending on authentication) URL fields do not collapse as they should when you are logged in.
- When signed out, you should get a Sign In, or comment anonymously in the comment section.
