can't ;-)

I stopped being able to spell after a few years using spell-checkers. Since Firefox started incorporating one, it has become even worse.

In second grade I won a school-wide spelling bee. Today I can't even fire off a proper angry comment on a message board without a spell-checker.

There's also the so-called Cupertino effect in which spellcheckers suggest words that are similar but completely wrong, e.g. "worker bees commanded by Queen Elizabeth", or "the third yesterday of January". Basically, one form of sloppiness or illiteracy replaced by another :)
