Stewart Mader of WikiPatterns is running a series 21 Days to Wiki Adoption, a series of video blog posts. I was really struck with his episode 4 about "Running a Pilot" His advice could be applied to any social media tool. The benefit of a pilot lets you help users get comfortable, develop the show me proof, and work out kinks. He advices including a cross section of users, not just early adopters. This series is based on his recent book, WikiPatterns, which is a must-have if you're considering a wiki project.
Has your organization launched a social media proof of concept pilot for any social media tool - wikis included. What did your proof of pilot look like? What did you learn? What advice would you offer to someone in designing a useful pilot.
