I'll be traveling to San Jose in July to participate in The Agile Experience. The slate of speakers looks great and I'm expecting to have a great time.
I suspect this is going to be one of those conferences where you're annoyed that you're speaking because you're missing great content in the next room. And when you're not speaking, there are multiple talks you want to attend at the same time. :) It's a good problem to have.
Early bird registration ends on June 25th, so if you haven't registered, don't wait.
