Hey Tom. When I wrote that post the last session about SEO guy, Matt from Google had yet to happen. I must say he had the best session. Prepared and gave tons of great advice to a room full of people who knew WordPress and blogging.
BTW, I have an article that I wrote that came as a result of being so annoyed with how much conferences sucked. It's entitled More Schmooze, Less Snooze: How to Deliver 'The Most Talked About' Conference Session. There's a PDF there to download as well. Feel free to pass along. :)
