Yesterday we were reminded that it is difficult to provide good activity metrics. Certainly Git commit statistics are a good means of indicating that there is activity, but different styles of development can leave very different impressions: a lot of very small commits leaves the impression that there is more activity than a smaller number of large commits. That is, when you just count commits, a one line contribution is equal to a 1,000 line contribution (skipping merge commits is a no-brainer).
