Social Marketing Guru and Author Mark W. Schaefer took time to sit down with MarketingMel at the recent SoloPR Summit in Atlanta. Mark has written the best selling books Tao of Twitter and Return on Influence. I first met Mark in person at SocialSlam. SoSlam 2013 is coming up on Friday, April 5 and I’ll be heading to Knoxville for it as I do every year. I hope to see many of you there. Meanwhile, MarketingMel got this interview “scoop” on Mark’s third and newest book, written with Stanford Smith, Born to Blog.
