@butter, @dessalines, I've grown quite fond of Friendica for that very thing, following things, not just people. Not only does it let me follow topics via tags, but things like #lemmy and #guppe get added as "forums", plus I can follow any #RSS or #Atom feed. All of these are added the same as adding any other contact (follow). All of these different ways of following things get listed in the same area of my account, as "contacts", where they can be easily separated into to multiple groups (lists). Each followed hashtag, forum, contact group, or protocol type is always listed down the side of my page where I can simply click on it to filter my current feed.
I know that other #fediverse / #ActivityPub interfaces such as #Pleroma, #Akkoma, #Misskey, #Calckey, #Hubzilla, and #Streams have some/all of these capabilities, each to their own extent. However, having played around extensively with all of them, I've come to find that #Friendica is the one that works best for me. And at the end of the day, this is the only thing that matters. It may be a bit time consuming, but trying all the things is the best (only?) way to see how they'll work for you.
So I would argue that not only the shutdown of #GoogleReader was the primary cause for the #RSS demise, but also this was actually intentional, to wipe out from the general consciousness the awareness of the possibility and existence of decentralized, user-controlled forms of content distribution.
Several users have also remarked that RSS and #Atom feeds still exist, citing podcasts as primary application (in fact, it could be argued that it's not a podcast if it's not available via RSS).
Looking up "Drupal" and "Notion" and I'm finding how to integrate with the Notion API and I'm like you don't understand I didn't want to work with Notion I wanted to reimplement Notion.
It's okay the urge passed. Just one of those ADHD "I've got a brilliant idea" moments
