Why RSS
What is RSS
RSS is a simple way for a server to provide a feed.
If you have ever seen this logo: 
, it indicates that the site supports RSS.
If you try to open the feed in a browser, you will likely get unrendered XML:
RSS has declined in popularity as sites like Facebook and Twitter have discontinued RSS feed integration. (Youtube actually supports RSS, if you open the inspector and search for ‘rss’ on a channel page, you will find a feed link)
This has resulted in a lot of commercial rss clients/readers like Google Reader being discontinued.
How to use RSS
You need to install an rss client, I personally use newsboat (a commandline rss client).
I can recommend Akregator from the KDE project as a graphical client.
A lot of sites have RSS feeds that can be found in the document metadata with the inspector browser debugging tool.
Why is RSS better than (Twitter, Reddit, Discord)
Social media sites have a lot of problems:
Celebrity gossip if your feed, often with no way to remove it.
Non chronological ordering
Surveillance of everything you do. (RSS servers cant see if you click on a post, just that you subscribed to the feed)
Random censorship or downranking for opaque reasons. On some sites you cant even use the word ‘cracker’ without getting downranked or silently removed.
