Harold - I went back and looked at a few of your other posts around this and reflected on some of the questions I get. There is a definite cultural change aspects, but I'm also wondering if we aren't shooting ourselves in the foot thinking about that aspect. I constantly recommend looking for pain points or opportunities to do things in small, isolated ways. Have a project adopt a certain approach. Start with a Wiki in a limited context and open up slowly. Etc.

Convincing people that a big cultural shift, management style shift, etc. is the way to go seems daunting. Convincing someone that there's a better way to address a particular work task doesn't seem daunting.
