But I actually think Facebook has broader ambitions with Groups too. My guess is that it’s a short-terms solution to a long term idea. That idea is that sharing will rule the web. Facebook needs a way to get people comfortable with sharing. And how do you do that? By letting you do it with your closest friends at first in smaller groups. But once you’re comfortable there, maybe you graduate to sharing with your broader network. And eventually, the world.
Ad-hoc networks. Not enterprise level but powerful indeed. Don’t see the Wave comparison though…. Wave went far beyond what Facebook Groups and Yammer can handle right now.
