I’ll be spending this week guest blogging for Fast Company. I am using it as an opportunity to dig into the participation economy ideas that I first posted about a few weeks ago. Indeed the first post is a redux of that original to introduce the topic to Fast Company readers. The next four posts will be new. I plan to explore metrics for a participation economy, transactions that support participation, health care reform and designing for participation. A few days after they appear over at FC I will also post them here.
