God is the details

As my friend Dominique Turcq said during his introductory speech to Dan Tapscott's talk in Paris two weeks ago:

In the networked economy, God is the details

One of my colleagues here at PwC gave me a good illustration of this yesterday.
He was speaking about a specific online Q&A forum at Cisco. It appears that when someone asks a question on this technical forum, only the first answer is made visible to all the participants. The following answers or comments are only visible to the person who asked the question in the first place.
Yeah. Great. So what?
Well there are several benefits to that. First, the forum is no longer cluttered and clogged by long threaded discussions and it can be used more easily by all as a FAQ system. Second, it encourages quick answers from people who want to increase their visibility and reputation. Third, it fosters quality, because people will think twice before posting nonsense.
Funny how little details can result in completely different behavioral patterns. It's the butterfly effect again.
