The general framework for our university research is the areas of coexistence, information and training that people make up in an online area. Web 2.0 has provided us with new tools to build spaces. Since the foundation of CityWiki in August 2006, we have explored the architecture of these places, which are articulated in a common space where, in the absence of hierarchy and police, action is defined by the empowerment and freedom of the responsible citizen. As a laboratory, since then, we have embarked on research and teaching activity in attitude 2.0 in the WWW. The first part of this article sets out the current empirically evolving thinking of our investigations. The aim is to understand the wiki territory as being informed and transparent, which is intended to add layers of information to reality in order not to replace it but to extend it. The second part then describes and analyses the innovation experience carried out during the 2007/2008 academic year in which a teaching model was tested in the modes and landscapes described above.
