If you've spent any time on popular news sites over the past few days, you may have come across the bizarre story out of Wisconsin about a 12-year-old who was stabbed by her classmates. While this is one of those things that are shocking on their own, it's made weirder due to mentions of "Slenderman" by the attempted murderers.
Of course, this led to everyone and his mother racing to explain to a confused general population just what Slenderman is, even though he's had a Wikipedia page since August 2012, had a Fox cartoon made about him, was a monster of the week (kinda) on Supernatural three months back and you can find Slenderman costumes in all reputable costume shops.
Okay, so maybe those references are still a bit obscure -- Supernatural is still a CW show, after all -- but it's still kind of funny watching CNN and the like using the same bits of information from the same sources to pretend they're up to speed on the Slenderman phenomenon. While they can certainly rewrite the same three facts with the best of them, none of them have been able to speak to why the creature is so popular with the Internet.
