Yeah, we can't blame Apple's autocorrect for not auto-correcting input errors.
Read past comments bud.

What's happening is that it's become more "flexible" in its learning. Society today (mostly today's youth) just loves to misspell words. "ur right" "I needz dat new fone"... crap like that, so I think they are just allowing any word that someone overrides to be stored as an "actual" word to appease the youth.
Personally I think they should leave it strict, or allow a separate "slang" dictionary/keyboard for the intentional illiterates to use.
That would be smart. And it does seem to learn new words faster. Just means we have to try harder to teach it.
