If you're headed to Agile 2009 this year, and you're at all interested in TDD, be sure to swing by my two talks: Test Driven Development in Java: Live and Uncensored and Continuous Testing Evolved.
The TDD session will be a lot of fun. I've found that solving real-world problems in front of an audience can lead to some unexpected outcomes which are usually entertaining and informative for everyone. Plus, it keeps me on my toes!
I'm hoping the Continuous Testing session will spark some discussion about the future of TDD, Continuous Integration and automated testing in general. I really think CT is the future of automated testing, and Rod and I are going to be bringing some great new research and insight to the conference for this session.
