Social media; becoming a trust agent

I've been reading a book recently called "Trust Agents; Using the Web to Build Influence, Improve Reputation and Earn Trust" by Chris Brogan and Julien Smith. I would have downloaded a picture of the book but my technological expertise failed me yet again! 

There is no question that social media is here to stay.  Facebook has over 103 million users in the US (more than 400 million worldwide), and is now the most visited website in the country, and Twitter is gaining influence daily. Social media has overtaken porn as the number one activity on the web. 

I have read several books on social media, but "Trust Agents" stands head and shoulders above the others. The book not only gives practical suggestions on how to get involved without it taking over your life, but also examines the importance of integrity and values in this medium. If you want to have influence,  become a trust agent by saying something of value that is designed to help others; promote others rather than yourself; create relationships rather than mere contacts. Reading this book helps you to understand the practicalities and the potential of social media.

The question is, how will we in the simple/organic/house church movement engage with our culture within this framework?
