>In the hierarchy of needs, a better photo sharing service is way down on the list. The problem with this line of thinking is that needs are a vector, not a scalar, and while one form of contribution may have a larger norm, all forms of contribution are eventually important. Irrelevant of considerations about the precise norm of the contribution-vector, soceity thrives on having people contribute in loads of different ways; if we were all oncologists there would be nobody who could treat heart disease, etc. I say do what you're good at, mostly, and charity where you can.
