I've been thinking about this subject considering comments made by a banned user who's name is a measurement, the thread about bruises and a thread I was in about eating. Sometimes we speak about members interests if they are a homogenise lump. However there thousands (if not more) members on a site at any point of time. Thousands of people each with differing tastes, interests and kinks. My experience has always been that one thing people are the most diverse about is their sexual interests.
Perhaps it is a better thing to consider "How many paying members are interested in X?" and "How many other models do I have to share/compete with for those members?".
