Via Substack's own recommendation algorithm, Substack Notes, and by perusing the leaderboards, both of which have been a thing on the platform for a while now. Substack's social media side is very Twitter-esque. Writers you follow "restack" publications (some of which are full of AI slop, unbeknownst to the restacker) and the algorithm also inserts "writers" you haven't encountered into your feed. ("Writers" is in scare quotes for a reason.)
