I made a list of the Ruby committers. The list is available in three formats.
The YAML version is written by hand. Other versions are generated by this generator. And you can also generate a HTML version by the generator.
The Ruby community is sometimes a bit too high-contextual. Who is "mput"? Who is "zenspider"? What does "why is why why" mean? What does it mean when ko1 says "the patch monster does ....".?
The list shows you who's who.
Many contributions made Ruby what now Ruby is. The honor of contribution for Ruby is not only the committers's. But it is sure that the committers are worth people to follow their activities. Follow them on twitter. Subscribe their blogs.
