sounds like a blog. you could try WordPress and use their Reader section to follow other Wordpress blogs. there's also writefreely and write.as

That's the original meaning of a blog. I guess platforms like Tumblr and Wordpress would qualify and can still be used for that. But the way they're actually used by most users has shifted quite a bit from their original intention. On the fediverse, something like friendica or even mastodon could work.

yes , check out writefreely and see reader section of that instance to read blogs made by people of that instance
