It just happened to be picked up by one of the comic news sites and went viral. Sigh.
And why wouldn't it? It's the most unique and "newsworthy" thing that there would be to report on.
Has FOX News fussed about it yet?
Whether it's touched on frequently or not doesn't have much to do with whether it's "in continuity" or not; for example, how often do they refer back to the story decades ago in which the United Nations issued Superman blanket permission to go anywhere in the world, into any country without carrying papers (on the odd notion that the U.N. could do that kind of thing)?
