Conversation around a URI?

If you haven’t checked out the new URI pages on del.icio.us (it’s been about a month) it’s worth a look. It used to look like this:

But now it’s like this:

The stated goal is to help people get at the “conversation around a url”. But it’s not a conversation if there’s no turn taking or response to what others are saying, it’s an aggregation of notes, except in rare instances where one is responding to another - which, while technically possible, is not often the case.

Calling this a conversation is simpler but there’s a lot more to it. It’s like collecting all the reviews of a movie. That’s not a conversation around a movie, it’s a collection of related information; the reviews primarily respond to the movie itself although they may also respond to other critics. To extend the simile, the critics who merit response are those who are most influential. You won’t often see the critic for the San-Diego Union Tribune responding to what the reviewer from the Sacramento Bee said, but both of them might note the criticism from Ebert and Roper.

And that’s assuming that people’s notes attached to a URI are about the URI. It’s often just a sentence or two from the page itself, or perhaps a note that deals with someone’s individual context. This is related info, quite useful in some cases, but it’s not a conversation.

I wonder if there’s a term for what this is? How about “subject aggregation”? I think that will take off about as well as connective efficacy.
