When are you going to put the Wiki back online? That should be a matter of a few man-hours of work. Until then, it's not believable to claim "We're working on updating the site and docs as fast as we can."
In my experience developing a couple of FB apps in the past, the information in the Wiki was absolutely crucial. (I'm talking about the Wiki that was located at http://wiki.developers.facebook.com/ in the past.)
