Common sense. When a person starts talking about casualness, specializations, posting something helpful or nice to know, or provides munchkinning classes there is always some 12 year old who thinks he can do better with something different. Except that something different is actually the same thing but using more coffee.

Videogames. They just aren't any fun when there is some 12 year old who thinks he can do better with something different. Except that something different behaves differently because the kid munchkinned its maximum.

Fun. There is always some 12 year old who thinks that it's better to max everything and use one trick to kick ass rather than playing around and actually doing something different for a change.
