I write here on my own site since only recruiters and related people will read here thus I target them where they are.
Medium’s great but since it’s heavy on politics, I do likewise. While many developers write there, most still host content on their own sites, usually .io (is .ai next?) ones hosted on GitHub Pages.
LinkedIn’s the place for professional and recruitment stuff, but I don’t want them to own my content and I can’t assure it’d be viewable given its AI recommendation engine.
WordPress only has my irreverent, miscellany personal posts.
Neither JSBin nor JSFiddle nor Github Gist nor CodePen ensure ownership or longevity.
So there you have it.
