@andralex proposed a "torrent" approach for reviewing PRs a while ago:
In the BitTorrent protocol,
you only get bits if you offer bits. In the envisioned "review torrent"
protocol, the more PRs you review, the more likely your PR is to get
reviewed. Do you think this could be supported by tooling?
I am not sure yet how tooling could help, but I am putting this here so that it's not forgotten and has a better visibility. Maybe someone else has a good idea?
