"Thanks for the kind words and thoughtful comment, Emanuele. No arguments with your thinking. Though I'd like to expand on one point and that's the Culture issue. Granted, its important but I think in the context of traditional approaches to leveraging collaboration where often it can look like a mission without a cause, exception handling (centered on good examples, similar to what you provide) is a far more tangible problem/opportunity set to start a practical discussion on where these new approaches to connecting people can make a real difference. And in my experience, the cultural challenges start to look far more palatable if the business problem is framed correctly to end users who want to get the job done right and are goaled to do so.   Thanks for pointing our references to the work of others. All very smart folks in my book." - Sameer
