Of the Troll...

Im afraid he is one of a very rare species, the platform-agnostic troll. As part of their rites of passage / coming of age / mating ritual they feel a compelling urge to prove that everyone else in the world is stupid/nerdy/misguided. Eventually the testes lower into a mature position and the hormonal imbalance is righted and they slowly adopt a fanbois colouration of their chosen platform, becoming indistinguishable from other NERDS. Enjoy this rare sight ladies and gentlemen.

On the other hand, his frequent use of the term 'nerd' could indicate that he is an O2 PR slug. :)
