There's really isn't supposed to be. The board has no unifying topic other than having given money to the site. It's just a VIP section, but there is nothing wrong with that. It also allows the people who actively keep 4chan afloat to discuss how they feel about the site without too many redditors and other outsiders spouting memes.
People who were willing to give money to the site probably spend a lot of time here and thus represent the core userbase a little more than the average poster.
