Check out what I was doing with http://gitspo.com/. Might give some inspiration. It is an aggregator of all mentions of open-source projects.

That's interesting, I've built a similar service, too - https://www.libhunt.com. You can see all the trending repos that people are sharing on HackerNews and Reddit. Also, if you click on any of the repos, you can see the exact mentions + alternatives.
