July 22-26 is the date for O'Reilly's Open Source Convention. San Diego is the location.
I've been enlisted by O'Reilly to try and make the Python track a success. But I can't do it by myself: I need people to help rustle up speakers and review proposals for presentations and tutorials. If you think you'll be able to make it to the conference this year, please consider helping out!

If you want to help, please let me know!
