Virtually every single website i visited for a week was shoving airbnb in my face. Yes, i know you exist, i went there.
There has to be more complexity to the 'rule of 7' because i'm sure there must be better sales patterns than just shoving 7 ads in a row for the same thing at you. The same thing happens with comedy central's online shows.. every time the same ad-- it just makes me hate the product after the first few times.
