One of the benefits of joining any MOOC is what you learn in addition to the course content itself. For example, the Web Science MOOC Blog has details of a Web Science Seminar at University College London (28 March 2014) as well as a Hackathon taking place today (16 Feb 2014) at Google in London for UK Flood Relief.
