Sometimes we forget that we really do live in civil society, where people generally get along, and that's to everyone's benefit. In particular, people use the Net and social media for mutual benefit in a big way, something I've observed every day for sixteen years doing customer service online. (Sometimes we need a reminder after dealing with the sensationalism of people who profit by trying to scare us.)
The Thank You Economy is about how the reality of our online lives reflects everyday values, like treating people like you want to be treated. It discusses how this applies to online business, how social media facilitates people geting along, and how that's really good for business. It provides real life success stories where people use social media for business, where the usual result is that everyone wins.
The Thank You Economy shows us the evidence that "business as usual" is changing in lots of ways, like showing that throwing money into advertising isn't as effective as just engaging people genuinely.
