Mindtouch recently named the Most Influential People in Open Source in their blog http://www.mindtouch.com/blog/2009/10/27/most-influential-people-in-open-source/. I think that it is a measure of the health of the industry that it is difficult to identify those people and it is always difficult to choose only five people. Mindtouch deserves the thanks of the industry for the survey and creating an excellent list (in the interest of full disclosure, I was named in the Honorable Mentions category, so how can I disagree?).
However, I think that they should consider splitting the list into a business and technical list since they serve very different roles in the industry. Congratulations to those honored!
