Libraries – Open Source Discovery Service
libraries.io
libraries.io
Couple of thoughts:
* Devise a "pagerank for packages" algorithm - number of Github stars, how actively they're maintained, number of issues/contributors/etc.
* For monetization offer a service similar to https://www.versioneye.com (found out about them on HN as well, after I had the idea). You're going to crawl the packages either way.
Best of luck!
Most of the time you already know the platform and want only to search for this platform, not all of them.
It must be a fun project to do still.
[edit] There's a 'see more' link that I missed.
