Big fan of feeds.

Feeds are a generic format, so you don't need that one client ("app") for this site and another client for another site and so on. Pick your reader or write your own. Once. Then fill it with content to watch.

It's decentralized, you can "follow" pretty much anything. (Social media promoted "you can follow everyone on our social network!" as a unique feature, but it already existed ...)

I consume pretty much everything through feeds, including aggregators like reddit or lobsters. Why would I want to open their slow web site or even be forced to log in?

It's a shame, though, that major browsers removed virtually every feature in the area of feeds. There used to be a little icon to indicate when a feed is available. Not even that exists anymore.

I, too, wonder which feed readers you guys use. There don't seem to be that many great tools available. Me, personally, I use a custom script based on feedparser (https://pypi.org/project/feedparser/), which grabs feeds and sends new items as an e-mail. But I have no idea how to "sell" the idea of feeds to "normal" people, because what are they supposed to use?
