When designers intentionally trick users into inviting friends or blasting a message to their social networks, they may see some initial growth, but it comes at the expense of users' goodwill and trust. When people discover they've been duped, they vent their frustration and stop using the product.
Michel Houellebecq
Of course, we can distinguish between males and females; we can also, if we choose, distinguish between different age categories; but any more advanced distinction comes close to pedantry, probably a result of boredom. A creature that is bored elaborates distinctions and hierarchies. According to Hutchinson and Rawlins, the development of systems of hierarchical dominance within animal societies does not correspond to any practical necessity, nor to any selective advantage; it simply constitutes a means of combating the crushing boredom of life in the heart of nature.
