constituo, ergo sum

Whilst reading this Wired article discussing why Google may have been willing to pay $1.65 smackeroos for YouTube, I came across what will definitely be the most high-brow groaner I'll see today:

"If you aren't posting, you don't exist," says Rishad Tobaccowala, CEO of Denuo, a new media consultancy. "People say, 'I post, therefore I am.'" Constituo, ergo sum. An interesting formulation that may well represent a new rationalism for the digital age. But for the moment, let's not put Descartes before the horse.
