Ruby is a beautiful language to write code in, and, thanks to Ruby on Rails, it's being used quite a lot in web applications. If you're just getting started with Ruby, be sure to check out our useful links. If you're already familiar with the language and want to jump right in with Yahoo!'s web services, we've got a series of HOWTOs just for you.
We've also created a new Yahoo! Group: ydn-ruby. Join up and get help, or discuss your favorite API tricks and techniques.
Finally, if you've built a Ruby-powered application, please consider uploading it to the Applications Gallery. We love to hear about your hacks!
