generally speaking you should always strive to use correct grammar for this very reason. When you allow yourself to communicate like an illiterate buffoon because you're spending a lot of time in the presence of other illiterate buffoons where it's the acceptable format, it inevitably leaks into everywhere else, such as communications with an employer or potential employer that values employing people that don't present as retarded. Same goes for quality members of the opposite sex, best not to present yourself as a circus clown in their presence.
Oh, and 3.07s on 33s is terrible.
