Hm, I don't think this thread should've been made. It serves no real purpose other than to have a chuckle (which isn't bad, when done somewhere more suitable, say the chats).
A noob/n00b is more of an idiot as Takis pointed out, while a "newb" is simply someone new to something.
It's my job to help the next generation, and set a good example for them. And for that I'll gladly lay down my life.
