Collaboration vs. Institution

I loved this view of collaboration, let the people who are using the information take responsibility for creating, posting, storing, labeling, etc. The comment about the programmer who came up with only one idea really hit home. It is a little of a quality vs. quantity argument. However, as a classroom teacher, this definition of collaboration would frustrate me. When we design collaborative lessons, the purpose is for each member to have a job that needs to be done. It is definitely more of the institutional definition of collaboration, and group members get very upset if they are the ones doing the 80% of the work while another member only does 20%. So...how do we reconcile the two?
