You can also socialize teams or “organic group” in the workplace whose size is limited by definition and whose success will be driven but the existence of a clear, shared, common purpose. I usually call it “sense and alignment”.

It also depends on the company’s culture : some are more likely to start with in-the-flow things because it sounds more like “real work” while some are ready to embrace a “full social experience”.

In my opinion a comprehensive enterprise 2.0 pilot should include both because companies also have to learn how to articulate. Small purpose driven groups and large interest-driven communties and networks, people being supposed to be a part of both depending on sense and their desire to expose themselves or not.
