Great idea, how often are you planning to run the stats and make the comparison ?
Keep up the good work ! Really interesting. I think you could add stats about commits (plus maybe issues treated) / cryptocurrency to see most active projects. Also issues that hasn't been revolved for some time, to see projects who are no longer being actively maintained. But really nice idea, it could be a nice addition for decision making.
