I guess you already know your you're that smart though?
I do write in complete sentences in formal publications. Bad grammar and spelling errors hurt your credibility. Being "smart" is only half the equation. You must diligently apply your intelligence if it is to be of any value. Many people achieve "top of the class" distinction because they simply worked harder than others in the same situation. Others may have been "smarter", but failed to apply it.
Aha, so now ya'll is sayin' you weren't so smart and ya gonna git uppity and say yous a hod worker? Either yous real smart or real stoopid.
