The community that grows up around a programming language is one of its most important strengths. Ruby has a vibrant, growing community that is friendly towards people of all skill levels.

If you are interested in getting involved, here's a few places to start:

Ruby User Groups
Your local Ruby user group is a great place to connect with other Ruby programmers. Ruby user groups are self-organizing and typically feature monthly meet-ups, a mailing list, a web site, and if you're lucky, frequent coding sessions.
Ruby Mailing Lists and Newsgroups
Ruby has an assortment of lists on various topics and in several languages. If you have questions about Ruby, asking them on a mailing list is a great way to get answers.
Ruby on IRC
The Ruby Language IRC channel is a great way to chat with fellow Rubyists. (Logs of past chats)
Ruby Core
Now that Ruby 2.0 is in the works, now is a great time to follow development of Ruby. If you are interested in helping, start here.
Weblogs About Ruby
Very little happens in the Ruby community that isn't talked about on blogs. We have a good list of recommendations for you to check into.
Ruby Conferences
Ruby programmers from around the world are getting involved in more and more conferences, where they get together to share reports on work-in-progress, discuss the future of Ruby, and welcome newcomers to the Ruby community.
