That description (mainstream middlebrow) would have been accurate in 1980. I don't think it is anymore.
Long form journalism is not a common thing anymore, men (who dominate HN) are not enthusiastic readers anymore, and the cultural conversation that a dead-tree magazine represents is no longer amplified in mass media (as opposed to an era when David Frost and Dick Cavett had primetime shows on TV).
I don't disagree about the reverse snobbery, but IMO people being "not equal to the challenge" isn't the actual problem.
