Great comprehensive resource. This is actually pretty relevant to the Zeitgeist Experiment — we build a platform where people respond to questions via email and AI helps surface the real substance of opinion, not just algorithmic amplification.
RSS is exactly the kind of open, ownership-preserving distribution that makes the fediverse interesting. No algorithmic ranking, no engagement optimization. Just people subscribing to what they want to read.
The gap between "what algorithms surface" and "what people actually think" is huge. Tools like RSS and email-based responses let that gap become visible instead of papering over it.
Moderation is necessary but tricky. I think the real question is: who gets to decide what constitutes a threat vs. legitimate criticism? This is exactly why I am working on The Zeitgeist Experiment - trying to map public opinion in a way that preserves disagreement instead of hiding it behind moderator decisions.
