If you're interested in recent innovations on this front: (rather than just retreading the same Web as before)
* Beaker (https://beakerbrowser.com) the peer-to-peer browser just released their beta release - and it has some exciting features. Particularly the built-in editor, meaning you can edit, serve and read your pages all from the browser. (Blogging in Beaker is as simple as visiting: hyper://a8e9bd0f4df60ed5246a1b1f53d51a1feaeb1315266f769ac218436f12fda830/. And the posts are stored locally.)
* https://special.fish/ This completely low-tech social network has taken off. The innovation here is that it's all just focused on profile pages - not feeds of random posts.
* There's a growing subculture of public Tiddlywikis (philosopher.life, sphygm.us, etc) - rather than focusing on protocols and APIs, they are much more focused on how to organize and style personal hypertext.
* As for RSS, well, as HN custom insists, I am also commenting to plug my own fraidyc.at. See, you knew it was here.
* There's also a forum on tiny personal link directories that's been forming at https://forum.indieseek.xyz. The idea here is to use Yahoo! or DMOZ style link directories at a smaller scale, to catalog corners of the Web. (Note that this whole comment itself is a kind of small 'directory'. Rather than an algorithm stepping in to show you 'related' stuff, I have.)

* On a related note, I've also been working on an RSS/Atom extension to handle ephemeral posts: live streams, "stories", pinned posts, etc. https://github.com/kickscondor/fraidycat/wiki/RSS-Atom-Exten...
