I call them all megaphones. And, as brand marketers, they are tools to hurt us – or make us. According to eMarketer, social networks are becoming the primary way mobile users exchange information. As of summer 2010, 63 percent of Twitter users posted via a mobile device. They instantly – and undoubtedly impulsively -- told us when a car salesperson pulled a bait and switch. And that their friends should get to the store quickly before the “must have” sold out. And that there was a cockroach crawling up the restaurant wall and you would be insane to ever go there. And don’t forget to tell your friends. This is a blog about the intersection between personal technology and what I call Moments of Trust, those critical touchpoints between a brand and a consumer that make or break businesses and impact sales and loyalty. We’ll examine the importance of customer service and integrity in business. We’ll salute some brands and chastise others for taking Moments of Trust for granted. It used to be that you could lose the battle for public opinion in two hours. Now it takes two minutes in an era where, according to comScore, 65 percent of the nearly 300 million mobile subscribers in the United States use text messaging. Without even making a call, those voices are being heard. This blog is intended to create a dialogue. Your megaphone is likely no more than four feet away at any time day or night. Use it. And hang on - my 80-year-old mother-in-law reads on a Kindle and she is eying my iPhone. The corner drug store is soon to carry a netbook and e-reader. Interactions with brands have never been so interesting.
