In this episode we had the great opportunity to talk to Jon Tennant, a fairly well-known Open Science advocate with many hats and even more projects. We talked to him about what drove him to Open Science, how it came about that he wore some of these hats and about his most recent (and community-driven) project, the Open Science MOOC. Jon has a thing with dinosaurs – be it the extinct species or legacy publishers in the academic world. And one thing became clear: he’s doing something about it.
