What good ruby gem sources would you recommend, besides http://gems.rubyforge.org/ and http://gems.github.com/? It seems that RubyForge is missing most of the gems I look for these times...
As far as I know, those two are it, with the primary being rubyforge, since that's the only source that a stock RubyGems install will search? As popular as github is getting, gem developers still can't yet assume that github has been added as a gem source, and usually provide specific instructions like
gem sources -a http://gems.github.com
gem install person-gemname
or
gem install person-gemname --source http://gems.github.com
UPDATE: gems.rubyforge.org, gems.github.com, and gemcutter.org have all been replaced by rubygems.org
Basically I agree that even if you are hosting projects on github or elsewhere all stable releases should be on RubyForge. The main reason is all the dependancies on gems, and it makes me happy when they are all in one place.

It would be good to add a RubyForge mirror - however I cannot find one that is up and RubyForge now (10-june-09) is down...
