I tinker on my own website and frequently write about IndieWeb related technologies because the web is my social media platform. The feed you might appreciate most is https://boffosocko.com/category/indieweb/feed/.
I have feeds for nearly every tag/category or post type on my site for convenience (just add
/feed/ to almost anything). You could subscribe to my firehose feed, but I suspect even my mother would tire of it quickly.
I’m curious if you have OPML files or similar bundles of feeds you follow that are shareable or subscribe-able?
