I like Scott Berkun's main blog and read it regularly. But now I'm also reading his new one that specifically covers public speaking. Lots of "how to fix" posts, and links to other tips and information. I was especially interested in the graph of heart rates falling as a lecture continued (in a university setting I believe) along with the recommendation to do something other than talk to folks every 20 minutes or less. Sounds like a good use for a demo!
