Quick note about the spelling thing - I agree on the whole, but you should be aware that there are glaring exceptions. Right now I work a lot with architects, for example, and many of them are very smart and yet have disastrous spelling abilities. Since I observed that there are smart people who can't spell, I've revised spelling ability down to "weak indicator" of stupidity or poor education. I.e., if someone spells poorly and has a few other things going against them, then the spelling will help decide the matter. But I would not make any rapid judgements on someone's intelligence based purely on their spelling/grammar.
