Ethan Marcotte is the man who brought the concept of responsive design to the web from the world of architecture. We would think that, in order to achieve such a feat, Ethan would have to know his tools inside and out in order to begin to use them to manipulate the world around him. But is that the case?

Big thanks go out to Jim Ray who helped organise Ethan as a guest.
