Control vs. Communication
http://www.37signals.com/svn/posts/272-control-vs-communication
Every once in a while we get an email from a customer asking about how permissions work with our products. They’re almost always asking how to prevent someone from doing something. “How do we prevent someone from posting a message or adding a to-do or downloading a file? How can we make our project site read only except for a select few?”
When we set out to build Basecamp we decided that it was going to be about communication, not control. It is our belief that when you collaborate with trusted parties it’s important for people to be able to communicate any way they see fit. Preventing someone from saying or doing something often breaks these free flowing communication channels and introduces miscommunication or silence—two cancers of collaboration.
