Lessig has posted a request for Creative Commons users to complete a questionnaire regarding the term "noncommercial."
If you are a CC user, take a few minutes and complete the survey.
BTW: I've always been bothered by CC's definition of noncommercial use because it attempts to define the character of the use (through the use of the term "commercial advantage") rather than just making it about free access to the work. I don't care at all if a for-profit entity uses my work as long as they are not charging for access to it and it is clearly licensed. For those that are interested, here's the relevant paragraph from the legal code of one of the licenses:
You may not exercise any of the rights granted to You in Section 3 above in any manner that is primarily intended for or directed toward commercial advantage or private monetary compensation. The exchange of the Work for other copyrighted works by means of digital file-sharing or otherwise shall not be considered to be intended for or directed toward commercial advantage or private monetary compensation, provided there is no payment of any monetary compensation in connection with the exchange of copyrighted works.
