I'm all in on RSS. Matter of fact, I used an RSS reader (netnewswire) to find this post!

I host freshrss on a linode vps so my read/unread feeds are synced across devices.

Hacker news, various subreddits, YouTube channels, webcomics, blogs, forum posts, and even a newsgroup (comp.lang.ada is still active) are all in there, letting me catch up on feeds that I choose to read at my own pace.
