Cab Broskoski and Chris Sherron are two of the founders of Are.na, a knowledge sharing platform that combines the creative back-and-forth of social media with the focus of a productivity tool. Before working on Arena, Cab was a digital artist and Chris a graphic designer and in this episode, they talk about their desire for a new type of bookmarking tool and building a platform for collaborative, interdisciplinary research as well as larger questions around open source tools, research as artistic practice, and subverting the norms of social media.
