Oddbean new post about login | logout The real problem is the flip side of that — new users don’t know whom to follow. IMO recommender algo is essential for large scale adoption, because it lowers the barrier to entry.
A recommender service that curates stuff on behalf of users and suggests that is a pretty good idea. The throwaway term "algo" is not really a good one because it means different things from different people and often it means a centralized thing built into the protocol.
Whatever you call it, a recommender system like this naturally drives centralization. It doesn’t need to be (and shouldn’t) on the protocol level, though.
