Grant Robertson of cc:365 (now up to 75 tracks) and The Revolution has been doing some in depth interviews with CC users. Check out John Buckman, Lisa DeBenedictis, and Scott Andrew so far. Buckman’s “most shocking revelation” isn’t all that shocking (read and you’ll see).
Also check out Ben Shewmaker interviewing Grant Robertson on the Spectrum Analysis podcast. Grant does a superb job of explaining and demonstrating the great things about Creative Commons as an interviewer, interviewee and most importantly as a tastemaker. Thanks Grant!
