I'm Tom Doberstein. I have to make a confession: I am absolutely addicted to social media. And that has been an excellent thing for me because this addiction has helped me become an expert in social media marketing. I never meant to become an expert in this subject, but I just couldn't help but strike up conversations with some of my favorite brands. Some of the conversations I have had with my favorite brands through social media have been very entertaining and have made me develop an interest in the ways that businesses can use social media and other Internet tools to promote their businesses.
