"As for your other example, I guess aggregating atomized information
in
the right context can make sense on the SERPs, well it indeed makes
sense. "

I think so too.  And I think the technological giant that is Google
might come up with a neat filter for the abusers, but I see value in
an aggregated SERP site search...thing (I just don't know what to call
it anymore), because it directly responds to a users search request.

Let's go back to my example.  Say a web searcher does a  search on
Google for "cool rock and roll shoes" which is an opinion, not a
fact.  It's hard to categorize products or content for that, but I'm
sure there are sites that might (did a search on it for c's a g's,
nothing even like my response) and my user's "tagged" an item that
way, but for whatever reason, say for programming acumen, I can't
supply a list of tagged results, but I can supply a searchresults.aspx?
tags=cool+rock+and+roll+shoes, which I'd like to, because here is all
my shoes that USER's think are cool rock and roll shoes.  It seams
this is in danger, when all I'm trying to do is give you a page all
about rock and roll shoes, i.e., relative content.

Very interested on how this plays out.  Thanks for the discussion.
