I invited some of my friends to discuss the nebulous concepts of coupling and cohesion in software design. How do we think about these topics? How do we understand the terms? How do we use that in our work as programmers? How do we teach it to others? How much does any of it even matter?

Our invited guests: Corey Haines, Curtis Cooley, Dale Emery, J. B. Rainsberger, Jim Weirich, Kent Beck, Nat Pryce, Ron Jeffries.
