One of the problems with the "viewed" relationship is that it can be
easily be gamed with just clicks -- whether the clicks are from a
programmed bot or a group of human clickers. With the "bought"
relationship you need to cough up some money, so gaming becomes
expensive and probably avoided!
For a while, before the recent US election, you would see a funny
dynamic with some political books on Amazon. It was first seen with
right-wing books[left wing bloggers pointed this out]. High on their
list of "recently viewed" would be left wing books, where you would
expect other right wing or non-political books. This happened with
newly released left wing books because they would not have as much
historic data as an older book -- less historic data, easier to
game. I don't know what the point of that was -- maybe one side was
trying to show "defection" from the other side??? This dynamic
disappeared as historic data accumulated for the books on the
original "viewed" list.
