I'd be interested in seeing the numbers on Amazon customer criteria -- there are plenty of reasons besides price. Two data points: 1) I recently bought a netbook via Amazon even though it was a new model and Amazon's price was near list and above most other search results -- because of their superior return policy and faster (semi-free) delivery; 2) I recently discovered some backpack clips I liked but declined to buy them at Amazon at $2.16 per clip because a search indicated I could get them for less than half that at REI -- and I would be near an REI outlet that weekend. In the first case I was sacrificing more than a couple of dollars for speed and improved chances of a satisfactory transaction, in the second the money saved was less relevant than the fact that I'd be near an REI store soon anyway and it's always fun to browse their aisles. Anyway, I guess my point is that there lots of criteria people use in Amazon visits and their Web usage in general. I visit Hacker News and Amazon "regularly" but it seems foolish to conclude from the frequency of my visits any correlation in my reasons or implied value, even if someone dresses up their SWAG with an allusion to a 1956 psych paper. From an entrepreneurial perspective, I'd be much more interested in contrasting customer usage of Amazon, say, with the Google "shopping" tab. (Amazon does its best to induce browsing of products beyond what brought you to the site -- how successful are they, I wonder?)
