Because you have to use words like that to let "n00bs" know that you will "p0wn" them with your "l33t 5k1lls". hehe, sorry. Like Tog_, i too could not resist. And no I don't talk like *that* even in online gaming.

But I do tend to use substitutions such as "ur" whenever possible simply because in order to type you tend to have to stop moving. And in most of the games I play online, the more time you're sitting still typing, the higher the chance you will get, a-hem, "p0wned". So by shortening words you save precious seconds of typing time. And to avoid further conversation on this off-topic topic, I type 70-80 words per minute. But when you are gaming, you're hands are not on "home row" so that adds to the delay.
