Free Tutorials out-of-date. Ideas?

This afternoon I went about updating the 'Learn Ruby on Rails' lens I look after on Squidoo:

It was woefully out of date because the number of tutorials out there that are up-to-date appear to be zero. I was wondering if anybody out there had something better than the ONLamp tutorials that could be pointed to do that don't cost money?

Failing that, if people get in touch I'd be happy to host a wiki and direct as a kind of editor-in-whatever to get a really great learning resource together for people who want to learn Ruby on Rails. If you go to the lens you can vote saying you would help, leave a note in the guestbook, or just contact me directly off-list.
