mixing up there and they're is just plain stupid, but accidentaly misspelling onomatopoeia isn't.
It's funny, in this context you present "onomatopoeia" as your example of a word that is fine to misspell, yet this particular word is like "Aluminum" a bastardized American degeneration of the
original word, (Aluminium/ Onomatopoetica) created by a large population basically "giving up" trying to teach it's original spelling and instead just rewriting the language.
This kind of laziness is much to prevalent in America.
I guess my point is, don't throw rocks in glass houses.
