OK, here's a specific mistake made by a rails committer in handling this issue. drogus closed [this issue](https://github.com/rails/rails/issues/5239) without bothering to tell GitHub about it. This meant that fewer people saw it, and fewer people had a chance to tell GitHub about it. (One even thought of telling them about it, but unfortunately suggested that someone else do it instead of actually doing it.)

I think that perhaps the Rails team should have someone reviewing that issues were properly handled.
