I tend to down mod rude and aggressive people on here and I also up mod people who I think have been down modded unfairly.
I am not sure if I am alone with my way of thinking.
Like in this thread, we can note the irony (and worshiping) of the community, with the top comment (11 points so far) done by anewaccountname, deliberately taking a piss out of PG's essay.
The fact that people here upmod/downmod based on whether they agree rather than whether it's insightful really bothers me. I think it's the wrong incentive structure.
