If they did change their 'format' ie. Decided to get trashed and a bit more freaky every week or so rather than the current'ish situation, at least we'd know when there's gonna be a 'show', if a bottle of something appears then 'game on', they'd get more viewers and replays for one night a week as people would know it's on, currently they'll be losing viewers due to people getting tired of waiting for something to happen when it can be a rare occasion.
The booze would help with the fact that although they enjoy it, they aren't lesbians and are only doing it for views which I'm 110% OK with, once a week or so isn't going to turn them alcoholic so they don't have to worry too much about health, and I'm sure Malia likes a tipple as well!
This is all assuming that most people are watching the site for the sexual interest and not for day to day activities that don't include getting naked and horny, I could be mistaken?
