Google's Website Has Vulnerabilities (and they want it that way)

I ran across http://jarlsberg.appspot.com/ the other day. It's a site that Google has assembled to teach anyone how to find vulnerabilities. It's set up so that you can walk through a live site and see exactly what kinds of things to look for, how they behave and how to fix them.

Why not get a few QA nerds (like yourself) together and work through these labs?
