Topic: Improve the RoR documentation!
court3nay over at ca.boose has set up a project to improve the Rails documentation. They're collecting money to pay some tech writers to get cracking on it, and currently soliciting donations. The fund hit $1000 in the first hour and is currently over $15,000!
I just kicked in $100 on behalf of Rails Forum, but anyone who wants to donate, that'd be awesome. Go forth, and contribute!
