Stumbled across Scott Hanselman's blog entry, "Tips for a Successful MSFT Presentation." This blog entry was from January 2003, but is totally worth reading if you give talks or plan on giving talks.
I am no expert on giving technical presentations, my experience being limited to the classroom setting, a handful of user group presentations over the years, and an ASP.NET conference. Does anyone know of a Web site for technical presenters similar to ScottOnWriting.NET?
