I just started a page at the below link that I'm lising a bunch of Virtual Earth Developer Resources that I know of. The reason I'm doing this is because there just aren't any really good lists of resources out there, and there are a TON of resources that you probably don't even know about. This isn't going to be an all inclusive list (that would be impossible), but I'll try to make it the best list of resources I can. Hope it helps some of you discover great content.
