We are moving from the world of relevance, where search engines dominate the web and users consume passively, to a world of resonance, where the user is a key co-creator. Data is at the heart of this transition, and particularly Open data is having a significant impact on the evolution of our social models. I have observed that open data has the power to engage citizens in important new ways, leading to increased collaboration and participation. At a time when populations express dissatisfaction with Government, any positive engagement is worthy of exploration and study. I will chart the recent history of open data and illustrate outcomes of several of the key events. Revelations that governments are routinely harvesting citizens' private data, as well as debates about the secondary use of data they hold, have impacted the open data agenda. These events have alerted citizens to the potential impact on their digital life, and have prompted civil society movements to join and enrich the debate. This additional collaboration is now moving the agenda towards policy co-creation with the citizen. With the use of social machines there is a real opportunity to advance towards an inclusive social model that delivers on the promise of web science: ‘It’s for everyone’.
