HBO: Game of Thrones: Homepage Testing GitHub as Blogging Platform

I'm subscribing to HBO just for the "Game of Thrones" series. Very seldom does a series inspire me to pay MORE for my video entertainment. (It also inspired me to read the books - http://en.wikipedia.org/wiki/A_Song_of_Ice_and_Fire) I just found out HBO is $14.95/mo. I'm pretty sure when I last cancelled HBO, it only saved me an additional $6. How is it that adding it back costs me more than when I dropped it? I'm also curious about HBO GO. Anyway, the plan is to drop HBO after the Game of Thrones season ends.
