RSS is still the best way to track the news on the web, and these RSS readers can keep you right up to date.
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.
If you're down to use Piped as a YT front-end, there's an RSS icon on every channel page in the top right corner.
If you want to use YouTube directly, use the following link and append the channel ID of whatever channel you want to follow: https://www.youtube.com/feeds/videos.xml?channel_id=
Another alternative would be using something like FreeTube, which can use RSS to fetch subscriptions (but doesn't by default unless you're subbed to a high number of channels).
