Why does everyone use PF as a representation of the game?

And where are YOUR sources? Because I can easily just come in and tell you that people tend to go on PF a lot more than sticking around in a static. Also, I wouldn't go for the registered playerbase, I'd go for the active playerbase. It's far fairer of a comparison.

it's just common sense
nobody is gonna argue with me when I say the official forums userbase comprise maybe 0.5-1% of the entire active playerbase
nobody would argue with me when I say raiders are maybe 1-5% of the entire active playerbase
and nobody will argue with me when I say pf is maybe 1-5% of the entire raiding playerbase
