Xperimentality

Seems like I am usually tweaking my presentations right up to the day I give them.  I am never completely satisfied with them.  I have been tweaking my presentation on AJAX that I am giving to the Huntsville .NET User Group this Tuesday. Some of the Mix06 topics I am reading over is making me want to cover a slightly different angle.  On the other hand, my presentation covers some under-the-cover aspects of AJAX that I think are important to know...even if in practice you may never have to worry about them.  Atlas and AJAX.Net cover up a lot of the details that I think are still important to know.  I am one of those that believe one should program for Windows using the Windows SDK at least once, just to get a better understanding of what is going on behind the high level code we typically write.
