Dynamic RSS feeds (or, to be more precise, the tagging and dynamic-listing infrastructure that would enable dynamic RSS feeds) would handily solve this problem as well.
Dynamic RSS feeds are the opposite of a solution to this problem; the mechanism that constructs a single conversational locus is broadcast, where everyone is watching the same 9 o’clock news, as opposed to decentralized communication, where different people are reading different blogs and can’t refer to particular bits of analysis and assume that others have come across it before. Contrast the experience of someone trying to discuss the previous night’s Monday Night Football game with another football fan and two gamers trying to discuss their previous night’s video gaming with each other; even if they happened to play the same game, they almost certainly weren’t in the same match.
The thing that tagging helps you do is say “this post is more interesting to people who care about life extension research than people who don’t”, but that means you don’t show it to people who don’t care about life extension, and so when someone chats with someone else about Sarah Constantin’s analysis of a particular line of research, the other person is more likely to say “huh?” than if they sometimes get writings about a topic that doesn’t natively interest them through a curated feed.
We might not be talking about the same thing (in technical/implementation terms), as what you say does not apply to what I had in mind. (It’s awkward to hash this out in via comments like this; I’d be happy to discuss this in detail in a real-time chat medium like IRC.)
