"Digital Ambassador" could be broken down in many ways.

The whole thing started as a two part idea, manifesto for how to show up at Google's party like a rockstar and the nuts and bolts of doing it. Part philosophy, part tutorial.

Philosophy could include: brand of you applied on the Web, listening strategies, how to play the networking game your way, recency-relevance-reference, the blog format as business card and living cv, technographic community awareness, finding your people, sharing your value.

How-to could include: set up your Google accounts, use them,  and appear on the front page, approach Facebook, Twitter, Linked In, post audio and video, set up a Blogger or Wordpress blog, integrate your network activity, use media effectively.
