Facebook heralds the advent of a society that mirrors what the social network claims to promote. Not a society of democratic exchange, where people interact within a virtual agora by opposing arguments, but a society divided by antagonism and defiance, one that is partitioned in isolated bubbles; not a society of free sharing of information but of commercial exploitation of the data we deliver each time we visit Facebook. Why should we turn away from this social network and all those who promote its paradigm? Because the proliferation of images encourages negative feelings, jealousy and intellectual harassment; because it distracts us from thinking in depth and it fragments our lives; because it spreads and strengthens the logic of ratings that leads to a superficial redefinition of the value of intellectual products and individuals; because it reinforces our preconceptions instead of confronting us to opposing arguments. The network invented by Mark Zuckerberg, who could very well run for president at the next US elections, poses a significant democratic threat.
