He then goes on to define a social entrepreneur as the residual claimant for an enterprise, but that in this case one prime residual is reputation and not financial gain. He cites some good examples and goes on to flesh out the idea more fully. Along similar lines I was just reading the Cathedral and the Bazaar (yes, my geek credentials are weak) and one section on Linus Torvalds and the creation of Linux really seemed to capture this point:
I'm sure this is all really well known to people by now, but I still find it fascinating and certainly worth sharing and talking about during Global Entrepreneurship Week.
The "utility function" Linux hackers are maximizing is not classically economic, but is the intangible of their own ego satisfaction and reputation among other hackers. (One may call their motivation "altruistic", but this ignores the fact that altruism is itself a form of ego satisfaction for the altruist).
Voluntary cultures that work this way are not actually uncommon; one other in which I have long participated is science fiction fandom, which unlike hackerdom has long explicitly recognized "egoboo'' (ego-boosting, or the enhancement of one's reputation among other fans) as the basic drive behind volunteer activity.
[...] We may view Linus's method as a way to create an efficient market in "egoboo"—to connect the selfishness of individual hackers as firmly as possible to difficult ends that can only be achieved by sustained cooperation.
[...] Many people (especially those who politically distrust free markets) would expect a culture of self-directed egoists to be fragmented, territorial, wasteful, secretive, and hostile. But this expectation is clearly falsified by (to give just one example) the stunning variety, quality, and depth of Linux documentation. It is a hallowed given that programmers hate documenting; how is it, then, that Linux hackers generate so much documentation? Evidently Linux's free market in egoboo works better to produce virtuous, other-directed behavior than the massively-funded documentation shops of commercial software producers.
