Standford Professor, BJ Fogg thinks so. In fact, he thinks it will have as monumental an impact on persuasion as the radio did over 100 years ago and told Fast Company why in a recent interview.
My favorite snipet:
“You have to focus on creating a spectacular product or service, and your market will find you. The people it resonates with will share it with others, and it will be distributed. It’s a big leap of faith for marketers to think they’re not going to have an active role in marketing. Once you figure out where it’s going, then you can start putting resources into continuing to go into that market or expanding into others.”

Sarah,
Thanks for mentioning the Fast Company article. You and your readers may be interested in my paper on Mass Interpersonal Persuasion. It was recently presented in Finland at Persuasive Technology 2008 and published by Springer. You can find it here:
