I bought the yearly sub, and i am usually one of those that will steal anything that's not nailed down if someone says its free. But the amount of entertainment and enjoyment that i get from the podcasts and other aspects of GB meant that i could not, in good conscience, not pay.  
 
i would not go to any other company and demand to be entertained by 5 random clowns for at least 2 hours without some source of recompense. so yeah i payed.. it also gives me a moral highground with which to judge all who appear before me.. which gives me a warm fuzzy feeling.
