Well not sure why, but it definitely didn't work for me. Random would have outperformed it. I like the idea though. Suggested github repos would be fun to have a look at.
Take a look at the repositories suggested, you may find it interesting after some digging or add a new liking to your list. After some more starring, the tool might actually start suggesting repositories to your liking.
Also if you find something strongly troubling feel free to create issues on the repo and I will try to see how it can be better tuned/filtered.
