Feed discovery is a challenge, but there are a number of current efforts to make it easier. Far too many to list here. Briefly:

There are curated lists:

- https://blogroll.org/

- https://minifeed.net/

Community lists (planets)

- https://planet.debian.org/

- https://www.planetpython.org/

Curated themes (like Bluesky starter packs):

- https://minifeed.net/lists

- https://www.youneedfeeds.com/starter-packs

Webrings are cool again:

- https://brisray.com/web/webring-list.htm

This collection of HN blogs is pretty good too:

- https://github.com/outcoldman/hackernews-personal-blogs

- https://blogs.hn/about

I've been trying to aggregate many of these into a giant list, https://alexsci.com/rss-blogroll-network/blogrolls/, which is especially focused on OPML blogrolls: https://alexsci.com/blog/blogroll-network/

If a website looks like a blog there's a high chance it has a feed and is probably using HTML metadata to advertise it, like this:

  <link rel="alternate" type="application/atom+xml" title="Atom" href="/atom/everything/">

Most feed readers know how to read that, so you can paste the URL of the blog itself into e.g. NetNewsWire and it will locate that rel="alternate" link and subscribe that way.

I view the webpage source and search for the strings "rss", "atom" and "feed" until I find one. I currently have 145 feeds. I follow blogs, news, I get updates about local events, I follow youtube channels, I get notified about new releases from various github repos, follow updates on various status pages, follow various subreddits etc.
