if you don't know the proper use of the words "there, their, they're", or "your and you're". your an idiot.
Here's the deal, attention to detail is important. And the dumbing down of society is becoming frighteningly apparent in people's inability to use proper spelling and grammar. Speak and write like a 5 year old if it suits you. But you lose credibility when you do, because you don't care to appear educated, how do expect to be treated as of you actually are?
