I wanted to suggest that you folks establish in-person, hands on training sessions. There are tons of ajax training courses (and everything else IT that you can think of), but it all seems pretty basic and nothing I've seen has been worth the time / money. If you consider pricing on the scale of some of the large shops (Gartner for example) you could easily charge $1995 or $2495 for 4 day courses. I'd certainly pay it, plus the airfare and hotel to travel to wherever you are, and I bet other corporate customers would as well. Just a thought to add some revenue. It's a great product you have here, and I think it would become more rapidly adopted if there were more avenues for the user base to learn / understand it (training classes, beefed up API docs and examples, etc).
We're already doing that, we just haven't actively advertised it yet as we're still preparing some stuff. Its one of the reasons that Jack brough me onboard.
Currently, we're only offering onsite training but we plan on expanding our offerings soon.
