Entrepreneurs! Take my money!
Let me publicly say something I've said privately: I will pay up to $1000/year for a subscription to a service that 1) documents the facebook APIs, 2) monitors examples and common usages and lets me know when they stop working, and 3) provides a weather report for the Facebook API servers letting me know when they're slow or sick.
Heck, I might pay more. We waste far too much developer time dealing with the problems Jobu so rightly points out.
