RSS is a great, albeit forgotten, technology. The problem is the social media-obsessed NPCs of the world don't know how to use it. It didn't help that all the major browser vendors removed the technology and you need a standalone client these days.
Let's not. Everybody has different amounts of time to spend on forming their opinion about a given topic. If there's a topic you care about, and someone hasn't yet thought about it as much as you, in no way does that imply they're an unthinking automaton and it certainly gives you no grounds to call them one.
It's not that forgotten. RSS feeds are my "front page to the internet", where I get my news, etc. Even HN.
Most sites (at least in the set of the ones I care about) have RSS feeds.
