Fedifeed implementation notes

Two components

Server implements a few endpoints
/reblogs — returns accounts that you reblog the most
/core_servers — returns the instances who host most of the accounts you follow
/favourites — returns users that you favourite the most

Client hits those endpoints, and then:
