I typed a post last night giving Taylor a hard time for his thoughtful invention of a new word, but for some reason it wouldn't post and it was time for dinner, so I just logged off. I've heard at least one fairly educated person use the non word "irregardless" and a lot of us average joe types. I guess under the usual conventions of the English language, the prefix "ir" would negate the word regardless in some way, so to mean the same thing as regardless, if you insist on saying irregardless, I suggest adding the additional prefix "dis" so the meaning is back to what was intended, that of regardless!
