Thinking about our discussion, I had the insight (!) that the way I figure out what is important or interesting is by observing what others think is important or interesting (or even funny) -- especially people I consider experts (or with whom I know I already agree). We're not doing solutions, but... If I could search for knowledge/information using a varietly of aliases, that would help me. I'd be willing to start with me -- some construction of my identity based on what I deemed to be my interests, projects, best work etc. -- and get whatever results that tossed up. But then I'd like to go in as Gary, or Anthony, or a famous author/scholar, and see what they would have gotten out of the same query. Privacy schmivacy.
