He goes through his slides, giving it his best, and gets to "Are there any questions?"

We still have IRC, but you can still wear bow ties and spats if you want. Today's thing is Twitter, and many conference suggest a hash tag by which you can follow and discuss the current goings-on. I've seen it suggested for a few things, and I've been disappointed in the past. I can only hope that it's a flyover-country thing and bigger events in bigger areas have more vibrant tweets. Purdue's BoilerWeb 2011 had some great discussions on the #bweb11 hashtag, and there was some nice interaction at Indiana Linuxfest.
