Why Do People Type Badly?

[Bridge]

But it makes sense in online multiplayer, especially in FPS games. Generally you don't want to do any typing apart from the courtesy "gg" at the end of each round but if you need to issue a general command to someone or just chat with people when things aren't too hectic, you want to spend as little time as possible typing. It's no excuse for using broken language, but things like no punctuation, all lowercase characters and acceptable abbreviations should be alright.
