What other bar were you hoping for? It's advertising. The fact that it works better than other kinds of advertising is a pretty relevant bar.

FWIW, since we're doing anecdata, I just checked my Amazon front page. Many things are irrelevant, a few comical (I recently looked at a 80-book box-set of Penguin classics[1], now it's systematically recommending each individual member of that box-set to me :-/ ) -- and a few are quite relevant and I clicked on them to check it out.
