The Javascript SDK is atrocious. I was writing a small score submitter for an HTML5 game I made (for testing, mostly), and they clearly don't care about their developers at all as the documentation is completely unorganized. I end up having to Google "site:developers.facebook.com x" just to find a function that fits what I want my app to do. Also, they refuse to update broken links to older pages and like you said, refuse to fix certain bugs that are clearly bugs.
