What is the 4th C?

Michael Dell talked about something else. Something beyond content, commerce and community.
Is there a 4th C? Has the 4th C already arrived? What is it? Is it Web 2.0 or is it something else?

In his keynote speech in the Southwest he said, "The focus should be on these three C’s: content, commerce, and then community. We think there is another stage after those three. We’re not sure what it is yet, though. And that’s the fun thing about this kind of technology. It is always changing and it’s a great opportunity for continuing innovation."

What is the 4th C....is it Connection, Collaboration, or something else?

Feel free to comment on what you think the 4th C is as it relates to home-based and internet business entreprenuers.
