Solving Open Source Discovery

I know a couple of open source project that have their own library ready for reuse, but http://libraries.io/ doesn't find them because they are not for reuse for npm, and the like. And if I know a couple, there are probably thousands. These libraries are not not re-use first, but project first, re-use second.
Another suggestion: Allow searching from a language sub-page, with results limited to that language.
Also, I would love to have an option to subscribe via RSS (I know that makes me seem old) instead of email.
I do really like how you're pulling release information and badge status from each project.
