We have reached a critical inflection point for open source.
With everyone from Qualcomm to UBS to Microsoft embracing open source in one shape or another, the question is no longer "why" to use open source, but rather "how."
Because of this changing mindset around open-source adoption, we no longer need evangelists encouraging open-source adoption. Adoption is a given. It's the default.
No, what we need now are those that can illustrate how to derive the most benefit from the inevitable adoption of open source.
This is perhaps evident in MindTouch's just-released survey of the most influential people in open source today, as voted by over 50 top-level open-source business executives. People like Larry Augustin, Marten Mickos, Dries Buytaert, Mark Radcliffe, and Andrew Aitken make the list. (Note: I am honored to be on the list as well.) They are there not because they're open-source cheerleaders, but because they have helped vendors and customers alike understand how to get the most from open-source investments.
