That's pretty idiotic, actually. Some of the smartest, most perceptive people I know are hopeless at spelling. Some people are terrible at algebra but find geometry is easy, some people are better with faces than names or voices, and some really, really smart people can't spell, no matter how hard they try. Hell, even people who are excellent at spelling tend to have a few words that are tricky for them for no good reason at all.

If they're spelling it cannon just to be cute, that's one thing. But discounting something that's otherwise interesting because of an incorrectly spelled word is, yeah, stupid.
