Resources for Learning Flex

We've got another installment on InsideRIA, this time it diverges from the usual content and is simply a list of helpful resources that I've run across on my journey into Flex. There's tons of info out there, but it's often difficult keep the helpful stuff organized. I recommend a maintaining a clear starting point from which you can navigate to whatever content you need at the time. As I continue to learn more about being a Flex developer, I'll surely run across more great resources and my list will need to be updated. To keep a handle on this, I've created a del.icio.us account for Learning Flex From Scratch. This way, everyone can compare the resources I've found to their own and possibly come across something useful.
