Substack and Medium "blogs" are the most soulless abominations to have ever exist on the Internet. Paragraphs of black text on a white background with constant pop-ups telling you to subscribe. Get an actual blog, either through self-hosting or on a site like WordPress.com (it's free). You get your own theme (even if it's pre-made) and no annoying pop-ups outside of banner ads that can easily be blocked (though I think WordPress.com allows you to disable them for your viewers if you pay).
I see zero reason to use Substack or Medium unless you want to paywall your content or avoid censorship (both of which can be achieved through self-hosting).
@Hephaestic >Substack is a known focal point for people who want to say something in the standard online political method.
That's my other beef with it. It's 90% philosophy/political blogs. At least Medium has blogs on things like programming, even though I wish they were hosted somewhere else.
Yeah, it sucks. The only fiction seems to be the aforementioned women posting micropoetry and that one guy who LARPs as a hobo living out of his van and fucking mid Asian bitches on the West Coast.
