The document summarizes a web 2.0 foresight exercise conducted by the European Commission to gather ideas for future Knowledge and Innovation Communities. It describes the 6 steps taken: 1) defining objectives, 2) analysing conditions, 3) scoping the exercise, 4) choosing methods/tools, 5) running the platform, and 6) following up. The exercise involved an online platform where over 100 ideas were posted and commented on over 7 weeks to inform the European Institute of Innovation and Technology's strategic priorities. Key lessons included the need for clear objectives, piloting tools, and planning for data analysis and platform follow-up.
