maybe it's because i was spelling bee (as well as speech meet) champ three years in a row during grade school... i have a good friend that claims to be a writer (just kidding, he's actually a very good writer), however he's a horrendous speller. he even teaches writing at a local university... what the fondue???!!! my best friend can't spell either - even worse via IM. at least i'm not the only one that thinks that poor grammar and spelling are bad... very bad...

now capitalization, however, is something i can do without (too lazy to hit the shift key!).
