We all have a good laugh at someone's embarrassing auto-correct typo (or maybe you've turned red by one of your own). But careful, concise writing that communicates exactly the intended message is critical, especially when the consequences for miscommunication are considerable. In the old days, poor communication could be blamed on bad handwriting. That's not an issue today since almost everyone types instead. But careless writing that is ambiguous, wandering, jargon-laden, or peppered with typos, is the new bad handwriting--and also just as unreadable.
