I've been thinking about community revenue models. What works best for different types of communities. I think freemium is the obvious choice for a lot of people. Pay for t-shirts or other items as a fundraiser, use those items as a premium for an annual fundraiser. Beyond that? Maybe offer a class/webinar that would be of value to a subset of your members. I wonder what else will come to mind at 3 in the morning. We talk a lot about proving ROI to our employers. But what about when the community is the business? Can you make a community self sustaining financially without bombarding your members with ads?
