"The news portion of the site is written by a group of editors who collectively write under the pseudonym"Tyler Durden" (a character from the novel and film Fight Club)...
Zero Hedge's content has been classified as anti-establishment, and economically pessimistic,[3] and has been criticized for presenting extreme and sometimes pro-Russian views.[1][4]...Economist and New York Times columnist Paul Krugman describes Zero Hedge as a scaremongering outlet that promotes fears of hyperinflation and an "obviously ridiculous" form of "monetary permahawkery."[17] Dr. Craig Pirrong, professor at the Bauer College of Business writes that "I have frequently written that Zero Hedge has the MO of a Soviet agitprop operation, that it reliably peddles Russian propaganda: my first post on this, almost exactly three years ago, noted the parallels between Zero Hedge and Russia Today."

Seems very credible.
