It's a free resource for learning/finding info on Ruby on Rails:
Click on “Try a learning drill” -the site will quiz you on Rails information to help you memorize- pretty cool. If there's anything else you would like to learn, you can search for, or create your own flashcards.
Will Bunker, who created One and Only, later rebranded as Match.com, created YoYoBrain to help him learn Web 2.0 languages more quickly- currently, the site has turned into a tool for any kind of memorization.
*I would love to hear your thoughts on site, as it was built on Rails. Also, feel free to suggest how to make this more valuable to people who want to learn Ruby on Rails (and any other programming language for that matter), corrections to the flashcards, how to get the word out, etc.
I hope you find it useful, and can't wait to hear your feedback.
