While I don't disagree, I still value tools like what the author posted. git log is a pretty powerful thing, and can do a lot of things; sometimes, it can do so much as to make it harder to see what you should do with it, and it's nice to see people's wrappers — even thin ones — that handle concrete use cases like this. His examples seem …prolific. I mildly hope his tool outputs something like "No commits for this author; must be out shaving the yaks" on the days when someone has nothing to commit. Perhaps he is working on a nicer code base than I.
