There are two big problems with these algorithms. Problem one is less controversial: small groups of propagandists game the algorithms to gain more exposure than they could get organically. Problem two is less comfortable: sometimes content that appeals to the majority does so at the expense of a minority. An algorithm that is purely democratic is only as fair as the majority is altruistic.
