If I was one of your readers, I’d much rather read on your self-hosted blog (bonus points if there’s RSS)… But I’m not. Since I’m neither a reader, nor the one who defines what fun means to you, I’m not sure my—and other commenters’—words should have too much bearing in your decision.
I say, do what makes you (and your readers) happiest. Even if medium is by some measure bad, I’d guess it’s “only” about as bad as every other closed-up commercial option—I think they all suck. Look into what you actually care about, though, e.g. privacy, then make your own call.
For what it’s worth, I agree with people saying medium is almost inexplicably annoying. I consider myself a patient person most of the time, yet nothing kills my interest in an article faster than seeing websites like medium full of dark-patterned cookie banners and popups and newsletters and signups on the other side of a link.
But maybe we’re simply the wrong crowd to ask.
Enshittification will often involve doing things like this, yes. But as the link itself states, the actual meaning—per Doctorow’s original definition—is an entire process, and a little more descriptive. These things are not the same, one is just frequently a symptom of the other.
Sorry if this comes across as pedantic, I’m in a personal quest, of sorts, to protect the original meaning because I think it’s too important to lose. To anyone else reading this: please, don’t use enshittification when you really only mean “the platform is doing something bad.”
For the quoted behavior, I’m a big proponent of “asshole design.”
