For those of you who want to get a great overview of ways to build relationships, both off-line as well as on-line, I’d suggest you read Trust Agents, by Chris Brogan and Julien Smith. What you learn are common sense ways to let people get to know, like, and trust you, and hopefully do business with you.
Most of the things you should already be doing in one form or another, but they show you how, by tying them all together, you have a better result. It’s an easy read, and they don’t bore you with the how to get the best out of Twitter or other social tools. They are concerned about the basic processes of building trust which will never change.
Gentlemen, good job.
