Recommended and mentioned products
Miniflux is a minimalist web-based RSS reader. It's very easy to use.
Newsboat is a fork of Newsbeuter, an RSS/Atom feed reader for the text console. The only difference is that Newsboat is actively maintained while Newsbeuter isn't.
I used to use InoReader and Miniflux, but have since moved to newsboat (https://newsboat.org/) and love it.
Reeder is an RSS reader and client for multiple services.
If you are on Mac / iOS, try https://reederapp.com. Can sync with several RSS services or sync with iCloud.
A desktop app or browser extension for Firefox or Chrome. You can use it to follow people (hundreds) on whatever platform they choose - Twitter, a blog, YouTube, even on a public TiddlyWiki
You should try https://fraidyc.at/. It's a unique tool.
Fast, clean and unique feed reader
I'm a happy customer of https://bazqux.com. It is a paid RSS reader that seems to be developed by one guy. The web UI is very good, and it's supported by Reeder, an iOS news aggregator app I use.
