First, a NYTimes article about web trolls and civility on the internet (http://www.nytimes.com/2014/08/15/technology/web-trolls-winning-as-incivility-increases.html?ref=technology&_r=1), and
Second, an article about the ad-based internet (we've seen this before)(http://gigaom.com/2014/08/14/is-an-ad-based-business-model-the-original-sin-of-the-web-and-if-so-what-do-we-do-about-it/)
It seems that public comments unavoidably have trolls, or they degrade very quickly until someone makes a reference to Hitler. So, is it impossible to have a substantive discussion online without trolls?
Where do you think internet trolls are wholly inappropriate, and where are they tolerable? Coding? Technology? Politics? Policy? Law? Religion? Would you put your money where your mouth is to have a serious online conversation without them? Are there any topics that you would talk about (or prefer to see talked about) on a website where trolls were paywalled out?
