This is a good point. We have a hypothesis that there is a care surplus (like Shirky's idea of a cognitive surplus) where there are lots of people that want to give back, but they can only give back on their own terms (i.e., when they are available and want to). We are very careful to not pressure folks into doing too much. Long-term this has to be sustainable. We are developing a strong listener community and that is helping people feel a real sense of pride in what they do and like they are a part of something larger.
