I'm actually an Engineer by trade, a profession which is heavy on the whole precision and completness (try designing a bridge that won't fall when built with incomplete or unclear specs) and in my profession we really don't care that much about correct spelling but do care massivelly about the clarity of the content.

Not saying that wanting better spelling isn't valid, rather saying that its some people's pet-peeve rather than an essential requirement for clear communication.

(Also I'm a non-native english speaker, been speaking and writting it for almost 4 decades, actually lived for over a decade in Britain, have tested as having a larger vocabulary than even most native english speakers and still make tons of spelling mistakes - especially around double consonants - and gramatical ones - misusing "in" and "on" being the most common one - which isn't helped by me knowing 7 languages most of which have different, somtimes contradictory, spelling and grammar rules - and I doubt I'll ever get it as right as the native speakers)
