I would like to see that somehow my "specific" tastes were reflected in the results. Amazin does this a little, based on the books others bought etc. I would like to be in a database of "taste-buddies" so that it was not just a return of results from, as in the book site example, of what is most popular among webloggers, but most popular among people who have chosen stuff like me. Stumbleupon may be doing this. I wonder how that could be linked to the Google and Amazon APIs?
