This is overall a good paper that will be useful to people hoping to develop workplace collaboration, so I'll focus on criticisms. First, I don't thnk you get to subsume 'network' under 'collaboration'. They're different types of things. People in networks 'cooperate' rather than 'collaborate'. Second, the deployment proposed consists mostly of telling, not doing. According to the paper, you have a collaboration leader, then you work with company leaders, then you implement the tools, then you start communities. Classic corporate deployment and OK for command-and-control environments, but for workplaces with any degree of independence you have to model and demonstrate the benefits. Via Lynn Wernham.
