What's the draw of ebonics?

I've been surfing around various LJ's and Xanga's lately, and am kind of taken aback by the huge numbers of people out there who either (1) can't spell, (2) choose not to spell correctly, or (3) are so busy trying to be cool that they opt for the whole ebonics route, which to me at least, is maddening. Maybe that's the point. Perhaps it's just me, but to read "Wha'sup yo peeps R U in to da MAXxxxxx an luvvin yo feelin an bringin da partay in ta da crazee beyatchizzz freekin git yo freek on" is actually kind of painful. I'm thinking if you're mentally able to decipher all that, why the hell aren't you mentally able to compose a sentence in clear (and correct) English?

Of course, the occasional ebonics-type words are to be expected (and forgiven) from anyone ("Byat, byat" is a case in point, as is "w00t"), but COME ON...I shudder to think that maybe the future CEO of my company will some day appear on Bloomberg with chains and a hoodie, sporting super-dark shades, and smoking a blunt. "Yo, 'sup BITCHES!!!! Da CEO's in DA HOUSE!!!!"

*sigh*
