If you actually want people to read long-form stuff you write, don’t put it on Medium. Just don’t.
There’s a whole bunch of alternatives, like these WriteFreely instances that are part of the Fediverse (the network that Mastodon also in a part of)
https://writefreely.org/instances
There’s also WordPress.com which has a pretty good free tier. https://wordpress.com/
There’s GitHub Pages which works pretty well too, if you don’t mind a little technical involvement. https://docs.github.com/en/pages/quickstart
There’s tons of affordable paid providers too. You get a lot for the cost of one bubble tea per month.
And of course there’s the option to run your own site, which is probably easier and cheaper than you think. It’s worth giving it some thought.
But whatever you do: definitely keep a copy of your writing in a place you control, even if it’s just a bunch of text files. You never known when or for what you’ll need it.
@esther for those who choose to run their own site, backdrop is a very decent and lightweight PHP-based CMS and what my blog currently runs on:
