I retired from the CEO’s office in 1994 and from strategy and marketing consulting last year. Other than a casual Facebook page with a couple of dozen friends, I knew little of social media until I discovered Twitter in February, 2011. That led to periodic posts on this blog. Thanks to social media, I’m re-engaged. I’m fascinated by the marketing opportunities afforded by the digital network and I’m impressed with the results achieved by the new medium’s best marketers. Back in my CMO days, I would have had a field day with social media. Why?
