Why @gccaedits? Ed already said it much, much better. I agree with Ed, and stand by his rationale.

I want to document what a wonderful example this little project is of open source software, permissive intellectual property licenses (Public Domain dedication in this instance), open data, and how all of these things together can change in the world.
In the two weeks since Ed has shared his code, it has 179 commits from 24 different contributors.
