I came across a very interesting post on the mmo-champion forums today. I thought it would be a good idea to link to it so as many people as possible can read it.
For a very very VERY small handful of you, say 5% of the WoW player base, most everything said in the post is pure common sense. For the other 95%, I highly recommend you read it.
I will say this, after playing WoW, I have found that common sense, isn't very common. That's why I link this thread.
