Meet Fifteen Ruby Core Committers

We all know Yukihiro Matsumoto invented Ruby, but how many of the other people behind Ruby can you name? Judging from this photo taken just a few weeks ago at RubyKaigi 2013, the Ruby 2.0 release was a real team effort, with commits both from the people on stage in Tokyo and hundreds of other open source developers located around the world.
