What happened?

Since when did netspeak become the acceptable way to communicate with people? "U" is a letter in the alphabet..."you" refers to a person! "Ur" does not exist. Try "you're" or "your" or even "you are" if you forget what possessive means. "L8r" ? ? WTF?!? Don't tell me we have gotten so lazy that we cannot bring ourselves to form whole words anymore!last Sunday
