Basecamp co-founders Jason Fried and David Heinemeier Hansson are back in the studio to answer your questions. This edition of Mailbag includes topics like why big companies don't use Basecamp; how they managed the transition from a web design agency to a product company; and what their business partnership means to them. Kristin Aardsma from Basecamp Support also pops in to answer a question about how her team maintains fast response times while making time for breaks.
