Thank you for your interest in my book: I love the fact that one of the examples (One Laptop per Child) has prompted further action and awareness. Re wikis…simply put, they are the end product of a collective effort: This makes them perfect for evolving projects like One Laptop per Child. By comparison, this blog is also collective, but the end product is a threaded conversation rather than a single document. Both are related: It’s really the difference in the presenting (or even existence of) a “conclusion” that sets them apart.

I am so happy that people are actually doing the exercises — you are providing an excellent example in this regard and at the same time spreading the word about a great cause. At its core, that is social media in action.

Wishing you a happy holiday-
Dave
