If you want to have a Medium-style text-based blog that people can follow on the Fediverse, you might want to try these:
You can either join an existing instance, or set up your own.
They federate with ActivityPub-based networks such as Mastodon, Pleroma, Friendica etc. so you can follow their blogs the same way you would follow a person.
do either of these support rss feeds? I didn't see anything on the homepages.
How come Plume is such a popular name? I already have 2 Plume apps on my phone 😁
mastodon.at is a microblogging site that federates with most instances on the Fediverse.
