With Rails in a constant state of evolution, it’s important for its users to help each other stay in step with what’s current. To that end, Conor Hunt has created Rannotate, a system for collaboratively annotating RDoc-generated documentation.

He’s gone a step further and posted Rannotate instances for both Rails and Ruby.

Read, post, learn, and teach. At critical mass, Conor’s service could provide a huge benefit to the community. Coupled with Kevin Clark’s Rails documentation crusade, things are looking better and better on the documentation front.

These guys deserve our appreciation and our support. Now go post some annotations!
