I just purchased a new domain name, “gitactivity.com”, to solve an old problem of not understanding what I’m working on anymore. Zillions of repositories (private and public), a bunch of commits, and then try and fill in your timesheets if you do that at the end of the week.
I hope it’ll end up being a free service for everyone. Developers should sign in with Github and observe structured (or even graphed) commits among various repositories.
