I think that when someone points a mistake, another gets offended like "OMG you can't point his errors, Stephen King is perfect, I love him, I hate you, you're going to hell, stop pointing them, I'm his number one faaaaan, Mister Man!".
And yes, maybe some douches intend that, but others only want to help, so through the Moderator, the publisher can print new editions with the correct informations (there were even threads here about this made by Ms. Moderator herself). It would be cool if people didn't point Steve's mistakes just to show off, and that the others didn't go offensive towards the ones who want to help...
All in all, these little arguments are just lollipop contests.
