This document discusses how natural history museums are evolving from monologues to dialogues by embracing social media and digital platforms. It provides examples of how the Natural History Museum of Barcelona is using internal and external blogs, Facebook, and other social networks to foster two-way conversations about science with staff and the public. By sharing content, stories, and expertise on these platforms, the museum aims to communicate more openly, learn from others, and establish itself as a public forum for discussion about the natural world. It also reflects on challenges like maintaining an active online presence and determining how virtual interactions could reshape the role of physical museums.
