I don’t think that RSS is a reasonable alternative for social media at all. Different use case for me.
I mean, I’d use it if I had a selection of known sources that publish content regularly that I like enough of to see all the content and have a website. Only a few sources actually meet that bar for me. Then, RSS lets me put a common interface on all of them, combines a list of new content.
I use something like Reddit or the Fediverse to take advantage of people finding useful content elsewhere, which is kind of a different use case.
I mean, you’re on social media here, rather than just following an RSS feed, so presumably RSS doesn’t replace social media for you either.
