I find myself checking github projects and their network, trying to see who forked it and has the "most popular fork".
For example, here's one of the best Nginx configuration projects I found, and it has about > 1000 forks. It would be great to be able to see which fork is the most popular, so that one can go and check other good solutions based on the current project.
Thanks for the recommendation! We're always looking to improve GitHub and very much appreciate the suggestion. I'll pass it along to our product team. While I can't say if or when something like this might be implemented, it will be announced in the GitHub Chanelog if it is.
