I get into arguments with a couple friends of mine over this kind of shit all the time. Your/you're, lose/loose, affect/effect...whether irregardless is a word. And working in IT, where communication with people is sometimes confined to the 'written' version of our language, it's amazing how many people are unable to correctly utilize the English language. It's not typos, it's improper word selection. And it's best when it comes from a VP or some director. I am the first one to admit that I lack proper typing skills. You will find typos in a lot of my posts. But for Christ's sake, if you're going to use a word, know how to first.
