Social media is often the least respected part of the marketing mix. With an internet full of cat pictures and funny home videos it’s easy to see why social media isn’t taken seriously by business leaders. This is a dangerous mistake because digital communication is disrupting almost every industry. Part of the problem is that most books on social media aren’t rigorous enough to have serious business credibility in unsexy technology and B2B industries.

So, where is the best thinking on social media today? It turns out that it’s hidden in plain sight in the business literature on word-of-mouth, competitive strategy and innovation. I’m a bit of a business book geek and I’ve read literature about business and strategy since I was a teenager. I started on Tom Peters and soon discovered Peter Drucker and Michael Porter. Seth Godin was a revelation for me. These days I devour everything from Mitch Joel and Hugh Macleod.
