Whatever the linguistic details, one of the main roles of RSS is to supply directly to you a steady stream of updates from a website. Every new article published on that site is served up in a list that can be interpreted by an RSS reader.
Unfortunately, RSS is no longer how most of us consume “content.” (Google famously killed its beloved Google Reader more than a decade ago.) It’s now the norm to check social media or the front pages of many different sites to see what’s new. But I think RSS still has a place in your life: Especially for those who don’t want to miss anything or have algorithms choosing what they read, it remains one of the best ways to navigate the internet. Here’s a primer on what RSS can (still!) do for you, and how to get started with it, even in this late era of online existence.
I don’t self-host (…yet. I do have a couple of things I’d like to play around with eventually) but honestly, for my use case I don’t feel any need to sync RSS. I mostly read articles on my phone, and if I’m on my PC I just remember which articles I’ve read. I can see how fetching RSS locally on each device might fall apart if one follows a large number of feeds, though.
