As you may or may not be aware, I spoke at the Orlando CodeCamp a couple months ago. After which I went to the "meet and greet" where Joe Healy and I talked about a bunch of stuff. Most notably was this idea I had about doing an Ajax conference. The end result was Day of Ajax on June 20th at the MS Offices in Tampa.
Joe Healy, Jim Zimmerman, and I will all be presenting.
Joe will do an intro to MS Ajax and will follow up later with a talk on Orcas' JavaScript integration.
Jim will do his talk on writing MS Ajax components (extenders, behaviors, controls, etc.)
I'm down for "best practices" which is a title I hate, but there's not a better title (I think that Ajax desciplines in some respects are too new to have "best practices" attached to them). As an I'm also going to slip in a couple mini demos/talks to show off some less demoed features in MS Ajax.
