From that site, I went to the definition of muckraking. I had forgotten where that term came from. Test your own IQ on great English literature. I was reminded by Teddy Roosevelt. Here is a short portion of a speech he gave--well worth reading.
April 15, 1906

In Bunyan's Pilgrim's Progress you may recall the description of the Man with the Muck Rake, the man who could look no way but downward, with the muck rake in his hand; who was offered a celestial crown for his muck rake, but who would neither look up nor regard the crown he was offered, but continued to rake to himself the filth of the floor.

Now, it is very necessary that we should not flinch from seeing what is vile and debasing. There is filth on the floor, and it must be scraped up with the muck rake; and there are times and places where this service is the most needed of all the services that can be performed. But the man who never does anything else, who never thinks or speaks or writes, save of his feats with the muck rake, speedily becomes, not a help but one of the most potent forces for evil.
There are in the body politic, economic and social, many and grave evils, and there is urgent necessity for the sternest war upon them. There should be relentless exposure of and attack upon every evil man, whether politician or business man, every evil practice, whether in politics, business, or social life. I hail as a benefactor every writer or speaker, every man who, on the platform or in a book, magazine, or newspaper, with merciless severity makes such attack, provided always that he in his turn remembers that the attack is of use only if it is absolutely truthful.
The liar is no whit better than the thief, and if his mendacity takes the form of slander he may be worse than most thieves. It puts a premium upon knavery untruthfully to attack an honest man, or even with hysterical exaggeration to assail a bad man with untruth. . . . http://www.pbs.org/wgbh/amex/presidents/26_t_roosevelt/psources/ps_muckrake.html
