But Marginal Revolution is well known for having the worst comments on the internet. Literally nothing but edgy one-sentence snark. It’s just a step above caveman grunts.
Marginal Revolution is more interesting than HN precisely because "X is widely believed, therefore X is true" doesn't fly as a line of argument over there.
Although of course they do lack civility.
Marginal Revolution is run by Tyler Cowen who is an economist. He has largely libertarian views and uses economic theory to justify them over the span of about a blog post. I personally don't think that's enough time to make a point about the sorts of things he talks about.
