I used to be opposed to the idea of social entrepreneurship. I said, you know, let business be business, and philanthropy be philanthropy. Keep the two separate, don't mix it up, and this is what I did, and I did that rather successfully, but I now recognize that actually you do need to mix it up and I think there is room for social entrepreneurship.
