I grew up online, and I knew that in every community there were trolls and tricksters. Like many people, I remained a believer. I thought the web was a meritocracy, and that the good stuff generally rose to the top. But spending serious time in the media underworld, watching as the same outlets who fell for easy marketing stunts seriously report on matters of policy or culture will disabuse you of that naïveté. It will turn that hope into cynicism.
