Watchub is a service that notifies you of people who followed/unfollowed you and starred/unstarred your repositories.
It runs every day and sends you an email if something changed.
The first commit was about 1 month ago, and I first deployed it to production exactly 1 month ago.
Since then have sent ~200 emails to ~30 users!
I guess this is a good number, considering I didn't promote it a lot (just to some friends and coworkers).
Thank you all, hope you continue enjoying it!
