a report, a business plan, a software release, etc.). This notion of work is a hang-over from the industrial age when work was mainly about production.
In this day and age, more and more work is about collaboration with others. Production is still here, but the centerpiece of work is the network of social commitments that makes production meaningful and valuable. Work is about having conversations with others (e.g., co-workers, suppliers, customers, business partners, the media, the government, bloggers, etc.). In these conversations we build relationships, invent and explore new possibilities, and coordinate action.
So where do we go to do this kind of work? I don't suspect that the answer is necessarily "the office." However, it is often far easier to collaborate when face-to-face with your collaborators.
As our understanding of "work" changes, I think our answers to Fried's question will change in interesting ways. I'm glad he's asking this question and I want to back up one step and add the question "What is the nature of your work today?" before asking "And where do you go to do your work?"
