While I love the idea of a Wall of Fame, could that go outside of the material? It was really hard to keep track of changes during the workshop because there were a dozen of pull requests to the original material, most of them just adding themselves to the WoF.
AFAIK, that was a first test run in which the material was getting fixed as well as being read. In the future, you might not have as many actual material fix PRs to look at, and only WoF PRs? So the issue might go away.
Alternately though, that’s exactly what happened for the Social Coding workshop. We have a separate project (with a specific ‘theme’ for commits) called underground.
