Facebook has metrics like, how often you browse that person's page, how often you comment on that person's post and vice versa. But could you apply it to GitHub where all you care about in Project X is Feature Y or Issue Z? I guess the easiest way is if you could somehow figure out that the pages the User was looking and commenting on all related to one thing, such as CSS issues or problems with C pointers and only display those issues. I'm not sure if that is doable but the people at GitHub probably don't have the necessary resources to devote to implementing this (at least in the near future), whereas Facebook has more engineers, resources, data, and time to throw at the problem.
