Not sure what counts as organic, but if I find a project that impresses me on github I often click through to their repos and scroll through to look for other gems. I found bottle.js that way a week ago.

I also cross reference people from Twitter if they seem smart. And I click back and forth between NPM pages and GitHub pages to see people’s work.

Some of that is pretty doable if they switched to Gitlab... except the Twitter cross reference, just because I would have to remember to search both gitlab and GitHub.
