The place I share most of my content is here on Being Peter Kim, where I've been publishing since January 2006.
In 2012, I co-authored the book Social Business By Design with Dion Hinchcliffe.
Earlier, I published nearly three dozen research reports at Forrester covering marketing strategy, social computing, advertising, agencies, and mobile marketing. I also created the company's Twitter account.
And for very short form writing, I'm @peterkim on Twitter.
