There are a lot of great open source Steemit projects out there and many of them don't have a lot of stars they they don't get the attention they deserve on Google or many of the open source discovery sites.
I am the developer for Gitlogs.com, an app that makes searching on Github and tracking projects a lot easier. I have added the ability to track Steem projects. I originally did it for myself as I'm just starting to play around with building on the Steem platform. I uncovered a lot of awesome hidden gems with the search and I hope you guys
