In these days, I read a book about ruby.
And there are some ruby communities and blogs.
Online Forum
This is a really cool forum, cause I found if you are in China, your ip will be denied to register the account. It looks like it is areally popular forum.
Especially the Sitepoint, It is a cool and poular online forum for web developer, not only included ruby , but also html5, javascript, php and so on.
IRC channel
#ruby-lang and #rubyonrails
they are all on freenode
rubyonrails maybe gone, cause I cannot join it.
usernet
[google groups]
https://groups.google.com/forum/#!forum/comp.lang.ruby
If you are in China, yuo need find a smart way to visit the google group.
Mailing list

You can easily subcribe it or teem all.

Ruby is a very cool programming language, I think these communities and blogs will help you learn it.
