> github for project discovery
Honestly I don't think I've ever "discovered" a project simply by searching/browsing github itself. Usually it is through places like reddit and HN, and blog posts when searching for how to do something. I've never gone to github and just searched for some random project name...
On the other hand I also don't use github "stars", which I see more and more people talk about, so maybe some people use github differently than I do.
