I agree, but keep in mind that this is a translation from French, I'd love to hear from someone who can read the original to see if they line up. I don't think it would change my mind, but it would be interesting.
The thing is, I don't see that much real consensus in "digital culture" because all consensus seems to end up being the lowest common denominator, which usually becomes some combination of self righteous indignation, fuzzy logic, "me too" knee jerking and cat pictures.
The Occupy Wall Street Movement was a perfect embodiment of digital culture, a generation who grew up always getting a prize for participating, and believing that everyone's opinion was equally valid. But without making value judgments of any kind, without choosing leaders, without any center except the comfort of the mob, you can never get anything done. There can never be a dialectic emerging from the clash between the old and the new. It's just another empty consumer culture dressed up as a social movement.
