Wikipedia: List of dates predicted for apocalyptic events
Gaze upon my favorite Wikipedia article of right this second: “List of dates predicted for apocalyptic events.” As one may be able to infer from the title, it contains a giant table of failed predictions for the end of humanity, the end of the planet, the end of the universe, etc. 169 of them at the time I write this, in fact. I counted. (With a computer, not by hand.)
To restate: Wikipedia editors have compiled 169 distinct instances of people being incorrect, most of them not notable in any way, and presented them as encyclopedic information. This article has existed for over a year and a half, and over 1,300 edits have been made to it. All solely to catalog people being wrong.
I hereby coin “wikismug” for those situations where you read something on Wikipedia and just know the submitter was grinning smugly as they hit submit. This article is some of the most concentrated wikismug I’ve ever seen.
