I should also mention that just because you *perceive* the data to be
meaningless, Amazon and its investors *certainly* do /not/. A doctor buying a
medical book isn't interesting, sure. But what if a dentist buys several
books
on intestinal surgery (Trying to roll with the analogy but it's hard :D) or
oncology. Or a Doctor picks up a few books on Pyrotechnics for a friend who's
into that stuff as a part time job, but gets flagged and put on a list.
Or even, a regular person buys a book about Free Software, and then gets
flagged by the NSA.
