ok.. who is the most important person in the adult industry money chain?
It's the surfer.
They pay the bills. To quote Joe Dirt: "It's the consumer"
Everyone who is part of the process to reach the consumer's wallet is important. If the content is shit, the design doesn't matter. If the marketing doesn't work and no one shows up, the content doesn't matter. If you can't make a purchase because the programming sucks, the marketing doesn't matter. Etc.
