Volker Grünauer, Ex- Wienerberger, liest " Social Media is Bullshit" von BJ Mendelson: "With a provocative look at social media, the book makes the point that all the Facebook friends and Twitter followers in the world mean nothing to you and your business without old-fashioned, real-world connections. Hard to disagree with that, but that does not mean that social media is a waste of time" (c) J.Boye
