There is a UI problem on GH with forks. (From my limited experience) most profiles that are full of forks the person just uses forks like they would stars. No branches or PRs made. I'd guess, cynically, this is to fill out their profile.

On the other hand a profile of meaningful contributions looks the same on the surface.

I've made a habit of deleting my forks after the PR has been merged upstream to the main repo.

So I'm actually in the position where I do have meaningful contributions to open source projects, but my Github profile doesn't show it (unless you look at my contribution activity).
