I did a presentation at CJUG
tonight on AJAX.
We had a good turnout, the talk went well -- and of course there was beer and pizza (thanks Sun and Borland!).
There is nothing like putting together a talk to force yourself to learn a technology: I used DWR
for my examples, its a very
capable and easy to use library. I think you might start seeing some AJAX techniques slip into some of our products :D
