I asked this question for the Q&A:

Non-profit organizations like SI need robust, sustainable resource strategies. Donations and grants are not reliable. According to my university Social Entrepreneurship course, social businesses are the best resource strategy available. The Singularity Summit is a profitable and expanding example of a social business. Is SI planning on creating more social businesses (either related or unrelated to the organization's mission) to address long-term funding needs?

I also recently asked this of Luke for his feedback post before the Q&A was up, and he mentioned in his response that SI is continuing to grow the Summit brand in a multifarious manner. Luke also asked me for additional social business ideas, citing a lack of staff working on the issue.

Less Wrong's collective intelligence trumps my own, so I'm fielding it to you. I do have a few ideas, but I'll hold off on proposing solutions at first. I find that this is a fascinating and difficult thought experiment in addition to its usefulness both for SI and as practice in recognizing opportunities.
