On the overhead of 'business models' | Martin Paul Eve | Professor of Literature, Technology and Publishing

"All of this is to say that running a business model is expensive in terms of time and money. There is a point at which it is cheaper to sink the volunteer labour and not to bother investing in revenue generation that may be more appropriate for small organizations. Once you start taking money, you need to set aside a portion of that income just to sustain the revenue-generating activities, rather than using the revenue to perform the original publishing activities that you wanted to do."
