Jaron Lanier: On one level, the Internet has become anti-intellectual because Web 2.0 collectivism has killed the individual voice. It is increasingly disheartening to write about any topic in depth these days, because people will only read what the first link from a search engine directs them to, and that will typically be the collective expression of the Wikipedia. Or, if the issue is contentious, people will congregate into partisan online bubbles in which their views are reinforced. I don’t think a collective voice can be effective for many topics, such as history--and neither can a partisan mob. Collectives have a power to distort history in a way that damages minority viewpoints and calcifies the art of interpretation. Only the quirkiness of considered individual expression can cut through the nonsense of mob--and that is the reason intellectual activity is important.
On another level, when someone does try to be expressive in a collective, Web 2.0 context, she must prioritize standing out from the crowd. To do anything else is to be invisible. Therefore, people become artificially caustic, flattering, or otherwise manipulative. (from interview on Amazon)
