I browse hacker news... It is what it is, I'm happy with it as a content sharing platform. My biggest gripe is the obvious advertorial/astroturfing that I think is probably something hn offers as a service, but I'm not stupid, so I ignore it.
I get news through economist.com and npr.org and scattered other sources. I don't feel overwhelmed by trolls, except when I read yet another fucking headline about gluten.
My social media is so boring and predictable I'll probably delete it all shortly. I've never had a problem there, but I respect that some people do.
I shop on the internet frequently. I get trolled by counterfeit goods sometimes! Also by fake reviews, but that's what professional forums are for in the post cluetrain world.
I get scholarly articles on the internet every other day as part of a professional masters program. Sometimes open comments on academic articles read like troll fests, but not really.
I participate in open source on github, that's not being trolled to death (Although big os project maintainers may disagree).
And on and on... The internet (as I know it) isn't being won by trolls at all. So what is the article actually about? Twitter? Comments on news sites (lol)? The pessimistic attitudes of "technologists"?
