Seems like a great idea. Small thing - I registered with Facebook and accepted the read permissions, but refused the write permissions (sorry, no apps get write permissions). Instead of saying "ok, we'll just ask again when you actually want to post something to Facebook," Dragdis just dropped me at a screen saying that I absolutely must give write permissions.

That should change. You should ask for write permissions, but if it's refused, ask again when it becomes necessary.
