In case you haven't noticed, there's a revolution happening in social networking with vast implications for e-commerce that extends down to e-mail marketing. I use the term revolution deliberately, not in the hyperbolic usage of many Silicon Valley vendors. I say revolution, because there's a radical shifting in the balance of power from a centralized authority - a brand, system or site owner - to the people. The Internet, through Web 2.0, has democratized the marketplace by empowering the individual. This has far-reaching implications on how ISPs calculate your complaint rate or if you are a "spammy" sender.
