No, man.  Think about it.  Not all of the "typos" were corrected.  This means that someone went to the trouble to correct some of them, but not all of them.  It would have been easy to correct all of the typos, but they didn't. Follow what I'm saying here.  It was deliberate that some were changed and some weren't. The question is why?  What message is being sent? C'mon guys, think about this logically.  Stay with me here.
