Proving once again that an "expert" is someone who knows only the slightest bit more than the guy next to him, I will be running a booth devoted to blogging. Basically, I will provide a 15-minute introduction to what it is and how to do it. Then I'll pass out a 1-page hand-out and take questions. This will go on for a couple of hours, I guess, and it should be fun. Obviously, I am really not an expert, but it will be worthwhile and fun. I intend to simply show how easy it is to create a blog and discuss some of the enjoyable aspects of blogging.
Heck, it could be a lot worse. Thankfully, I'm not going to be in one of the really difficult booths, like the one where they'll teach you how to set the clock on your VCR/DVR.
