I'd hire anytime a guy who knows how something works over someone who knows how to correctly spell the name of that thing, or even knows how the damned things is called. These things are very frequently closely related in at least one direction. Useful as a filter. I've known people way smarter than I am that have way worse spelling, grammar and even basic communication skills than I have. It isn't really the rule, though, is it?
