I'm glad I looked at this list, hadn't seen a couple of these projects before.

It should be called 2009 Ruby Top Ten, but interesting all the same.

Only three of the ten relate directly to Ruby (Unicorn, Gemcutter and yajl-ruby) - Homebrew also happens to use Ruby but is useful outside the Ruby community.

As a non-rubyist, I think it's a pretty good list.

It's more of a Ruby and JavaScript top ten. This is clearly subjective, and a personal top ten. This should be made clearer in the title.
