No filtering. No comments. No proposal. No central way to find them.
It's not the absence of curation.
It's my curation.
It's easy: I like a site, I want news, I get the RSS. I delete it when it's not to my taste anymore.
The basic, deterministic, manual aspect of it is what's right with it. Not what's wrong.
Another weird idea is that RSS should be for everybody. No. It speaks to a certain kind of people, and that's fine.
