title: Should I switch to Rails 3 now?
body: <p>According to their blog (<a href="http://weblog.rubyonrails.org/2010/7/26/rails-3-0-release-candidate" rel="nofollow noreferrer">http://weblog.rubyonrails.org/2010/7/26/rails-3-0-release-candidate</a>), the release candidate for Rails 3.0 is out now, and the formal version will be coming in 'a few weeks'. I've been planning to rebuild my application using MongoDB anyway, should I go ahead with Rails 3.0.0.rc right now or wait for the formal version?</p>
