Winer advises web entrepreneur Jason Calacanis -
"..he needs to figure out a way to build the company so that many others can profit from it."
What impresses me so much about the comment is that it truly is the perfect definition of "Web 2.0" The companies that are succeeding today are those that are open and allow other companies to be born, and to succeed as well, off their backs. This is what the open API movement is all about. Sharing the information and ultimately sharing the profit.
Google is worth billions, but there are probably hundreds of companies that are worth hundreds of millions, and thousands of companies that are worth millions, that were created because of Google. As Winer points out, Google is a success because others can profit from it. The more they share the wealth, the more valuable they become.
Historically we think about building companies so that we (management, employees, and investors) can be the ones to profit. But as Winer points out, there's now a fourth party that needs to be in on the action - the community.
Sage advice indeed.
