Fork discovery is a serious issue in cordova mobile plugins world. I think people go native at one point and abandon their repos :)<p>Ad article, another point is that someone might have a manually created fork, without the link on github, or they asked GH support to unlink the two repos (because they want to be perceived important, not just a fork etc). Not sure how to handle that case well and if GH will invest time in that.<p>For the discovery of forks: I think an interesting feature could be some heuristic like: IF no commits in N months && there is a fork with at least M stars and K commits forward THEN list top 3 forks on top of repo's readme, on a distinct background (say, yellow) with a message: Hey, you might be also interested in these forks: A, B, C.<p>Having said that, I think it's a very low prio for GH probably.
