Both Creative Commons and the Wikimedia Foundation are searching for new CEOs. These two organizations are "anchor institutions" of the emerging digital civil society that we're all busy inventing/experiencing/trying to understand.
I've never done this before, and am only doing it now because I believe so strongly in both these organizations - here are the links to the two job descriptions.
CEO, Creative Commons
Executive Director, Wikimedia Foundation
Both organizations are using headhunters to find the right candidates - please follow the information on the linked job descriptions to apply. I have nothing to do with these searches - I'm just a vested member of the broad community that depends on these organizations and their work.
(HR/PR people - please don't send me your job descriptions for posting here. I won't do it.)
