Hi there, we made it to the third episode (a bit late though, Moritz was travelling to SXSW).

In this episode we first answer to some of the questions we received and then we move on to the main topic: how do you evaluate visualization? We have been discussing some contests in episode #2 and thought evaluation is really a key issue there.
