Just watched the Robert Scoble interview of Adam at Dreamforce '06. Scoble, formerly an evangelist at Microsoft, asks Adam some pretty good questions about the Apex platform and Apex language, and the result is a geeky but fun 20-minute conversation about on-demand development. (At one point, Scoble actually says "Emacs or die!".) There's also a video posted of Adam doing a demo, though you might find this screencast to be a little cleaner to watch.
