Not sure what you mean by "dogma". Maybe its not the right word? Perhaps you mean a resistance to new ideas or prevalence of group think?
Forums like this tend to produce "Accepted" solutions that are argued blindly for. I certainly mean dogma.
I'm surprised at some of the headlines that make it to the popular page. Not sure what to do about this. Maybe it can't be completely automated. Maybe there has to be some amount of manual curating of stories.
