Enterprise 2.0: Is it about Groups or the Individual?

Michael Idinopulos’s latest post on Transparent Office compares two different responses about Enterprise 2.0 adoption.

One of the statements being compared is from Stowe Boyd’s post:

I disagree with the notion that Enterprise 2.0 is about groups not the individual. On the contrary: Web 2.0 is based on the person and personal relationships in networks, not group membership.

The 2nd post compared is from Michael Idinopulos himself:

Enterprise 2.0 posits the group as the primary unit of activity; email posits the individual

What’s your take on it? Is enterprise 2.0 about the group or the individual?
