So I spoke at GSP Developers tonight on TDD. It went well, though I was a bit nervous. I got through the example I chose with less code and fewer tests than I had with any previous attempt, though I still took about the same amount of time. I enjoyed the questions from the audience, and the event organizer made some great observations as well. I think I might enjoy doing something more long-form, such as a mini code-camp for teaching TDD.
