Interesting reading, Tedster, even for those of us who haven't studied math (or thought much about it) since high school.

One question: You said, "In a given market, the pre-measured norms will be different. Because this is so, it will seem like one website can 'get away with' practices in a given market that would hurt another website very badly in another market." In the context of that statement, how broadly or narrowly would you define (or do you think Google might define) a "market"? Are you thinking of very broad categories like "widgets" and "bookings" and "real estate" or narrowly-defined niches?
