I have been known to mock the occasional misspelling. I can’t explain why I do this. I recall vaguely from years ago that I read somewhere that spelling is not related to intelligence and can vouch for knowing people who are smart but fairly terrible at spelling. Much as I can’t explain why I might mock a misspelling, I likewise offer no insight as to why I generally do not have to look up a word in order to spell it correctly.
I am, however, ready to blame the Internet for making the general level of literacy (and spelling) that much worse. It’s a convenient scapegoat and it comes with lots of circumstantial evidence, like The Best Obnoxious Responses to Misspellings on Facebook. It’s quite possible every entry on the site is faked but they ring true.
This is almost like a comedy routine (warning: salty language):
Me, I don’t fuss over the occasional typo. I might raise an eyebrow when I see ‘rediculous’, I may open my mouth as if to say something after spotting a your/you’re slip. I pretty much pass right over its/it’s since that one just underscores how arbitrary and strange English is, anyway. But I do offer one warning:
‘No one’ is two words. Noone is not, unless you are maybe referring to Peter Noone of Herman’s Hermits.
