First, we’ll fire all the introverts!
A friend of mine was telling me yesterday how people are inevitably attracted to social networks, social media and social tools because humans are social creatures. Obviously, if work is going to be more social and collaborative, then knowledge workers certainly need to pay more attention to social and collaboration norms, skills and behaviors.
But what are you going to do, fire all the introverts? We should be very, very skeptical of the social enterprise if it doesn't recognize that a lot of your most valuable and talented employees aren't the ones chatting around the water cooler. Introverts are very often the low maintenance people quietly getting things done, bringing a sudden insight or innovation to the team, or watching your back while you make an ass of yourself at the staff meeting.
I also feel really, really strongly that all of the critical, creative conversations are wasted when people do not balance the increased social time with an equal increase in quiet reflective time to absorb and process new information and ideas. Even extroverts need to sit quietly by themselves every now and then. Conrad said, "We live, as we dream—alone." No matter what anybody says, I still believe that we also learn alone just as much as we learn together. The wisdom of crowds depends not on us all knowing the same things, but on all knowing something that others don't.
My take on the social enterprise is that collaborative work can be more valuable but at the same time, it's often less productive in the short term. I think that successful collaboration in business environments really comes down to two complementary sets of issues.

To work effectively in today’s collaborative knowledge environments, we need to have communication, presentation, persuasion, listening and learning skills for different levels of social interaction. I think that, a lot of times, the skills are completely different from one level to the next: 1-1, 1-many, many-many, many-1, and then just 1.
