medium had one killer insight, which was that if they dolled up blog posts to look like prestige news site articles, most people would mentally put them in the same category. at one point there was a wave of public figures using medium basically like they use/d the nyt oped section before and after

but they messed up their site chasing a business model, and nyt/wapo/etc basically turned into tech companies and fill the niche that medium wanted to. meanwhile substack mints prestige by emphatically not looking like a news site. medium doesn't really have a place on either end of that anymore
