The recently introduced StarterPacks so people can collect groups of accounts on a topic for new users go quickly find and follow.
They seem to be holding off on indexing these, as well as the block lists, to prevent abuse. I saw they wrote that somewhere, but cannot find it at the moment
I have trouble finding people or feeds worth following, but give it time. The same was true for Twitter when I started.
My one recommendation: the Moss feed is agreeably chill.
