Agreed. I've been working with their API for the last 2 years. When it does break it can take forever to get a response. I work for a Facebook preferred developer so we have an extra channel for getting bug feedback. If we weren't a preferred developer, we would have had API bugs go unaddressed for months. Sure there were warnings about some changes, but sometimes major changes occurred that we did not see coming and had to scramble to figure out workarounds.
