Nothing, and I aim to keep it that way.
I like the articles, I like the forums, but that's the extent of it. I very rarely watch the Quick Looks and to be honest, I can't get through five minutes of the Bombcast (Have tried to many times.). I don't feel the need to spend money on a shirt to show off a site whose "best" features I don't enjoy.
I like the guys, I really do. I follow them on twitter and they're great guys, but, I don't like them that much.
