There's always going to be a tradeoff between trolling and anonymity, and I guess that's the way life will be. And you can manage it, but you can't cure it.
Tim WuWhen you think about normal advertising, it's just like, hey, here's a car and, you know, we don't know if you're looking for a car or not. So Google promised that mental state, and then were able to prove that delivering the message at the exact right moment would make someone click on something. So they pioneered the idea that advertising could be profitable on the internet, that a specific, very micromental state could be targeted. And they established the primacy of the click, which has haunted us ever since.
