Thanks to online social media such as blogs, social networks, or curating tools (like scoop.it), lots of news has been published, commented, re-published, re-commented, etc. One no longer needs to graduate from journalism school to be a science editor or reporter. That is to say that a new generation of science web journalists and science content managers is appearing. How does this evolution of the traditional role of a mediator impact our behaviours in science museums and centres? How could we benefit from a renewed relationship with these science web journalists? This panel session will give voice to innovative experiences at the crossroads of social media, web journalism and science centres.
