Actually, it's sad to say, but that post was one of the better written ones that I've read all season. Word usuage, spelling, and even grammar were all done fairly well, if you take into account that it intentionally uses more colloquial dialect. You're fault is in assuming that because it's in all caps and because it didn't sound prim and proper it was written poorly. Read Mark Twain. Not much difference between the two. He claims that he dropped out of school? Well, I've got to applaude him for his writting skills because, to be honest, they were quite good, even if it was written in a layman format.
To be fair, most of us are a bunch of idiots and play ball rather than write properly but even this is something a junior high kid could critique
"AINT WINNIN NO GAMES FOR ANYBODY"
But I guess when other idiots give you props you deserve it.
