The curl project has been hosted on github since March 2010, and we just now surpassed 5000 stars. A star on github of course being a completely meaningless measurement for anything. But it does show that at least 5000 individuals have visited the page and shown appreciation this low impact way.
5000 is not a lot compared to the really popular projects.
On August 12, 2014 I celebrated us passing 1000 stars with a beer. Hopefully it won’t be another seven years until I can get my 10000 stars beer!
