I don’t believe that there is an equivalent in academia, one that would capture the h-index dynamic (copied by PageRank) that a star from a prestigious professor is worth a lot more. It’s trivial to build, but “growth hacking” for lack of a better word, is hard, especially in areas where actual growth hacking would be frowned upon.
That’s why, for instance, Facebook celebrates its billion of users so much: it’s genuinely hard to make that. Hosting them too, but not in the same way.
