That has always been my understanding, newb/newbie refer to someone who is genuinely new to the game, but wants to get better. noob/n00b are used to slate someone, for doing stupid things, when they should know better. Unfortunately though now that mmo gaming has reached the masses, etiquette has gone out the window. Most people just hurl "n00b" at anyone regardless of their abilities, so it has become derogatory and used to insult people. The problem is, as Cliff says in the article, to many people just want to insult people rather than giving them constructive criticism.
