It was a great conference and I still need to get out there and get all of the code samples that were put out.
Rick Strahl had a great session on AJaX and also a few good sessions on other Web Items. If you went to the conference and you need a good pointer to that stuff, look here.

Dino Esposito gave a couple of great presentations, but I have not seen his slides up on his site yet. It is possible that he only put them up on the conference link.
