Actually, the response to that typo made me think of an experiment I once heard of that dealt with how we read words.
Basically, it showed that when we read, it's the first and last letters of the word that matter the most.

That kind of makes sense then that we all read "cyclon" as "cylon" instead of "cyclone", because of the missing "e" at the end. I'd bet that most of us would have read "cyclone" anyway if it were the second "c" that was missing.
