One of the perpetual questions about Summer of Code is “Why can’t there be documentation projects?”, since most open source projects need docs as badly as code.  There’s various reasons that I’m too lazy to research and type out, I’m sure, but Google is sponsoring a “Doc Camp“, in October.  You don’t have to be in Summer of Code; you just have to be willing to spend the 17th through the 25th writing documentation.  Google pays for room and board, and you can apply for transportation cost coverage.  A classy idea, all around.  Someone participate and report back!
