The exposure era

 “One of the chief requisites of a successful author-exposer is that he shall take himself and everything he touches most seriously. An appreciation of the humorous would be likely to mar what would otherwise be masterpieces of exposure literature. … He takes the world seriously, he demands to be himself taken seriously, else he may brand you as one of ‘The System’ or a sympathizer of that aggregation of corruptors.” — The Exposure Era in the Magazines, St. Louis Post-Dispatch, April 8, 1906.
