Saw Gary Vaynerchuk on CNN. Seems on target, but you decide... (check out link above)

"Everything has changed. The social media revolution has irreversibly changed the way we live our lives and conduct our business. There are billions of dollars in advertising moving online, waiting to be claimed by whoever can build the best content and communities. Despite this change, most people keep working at jobs that don’t make them happy and businesses continue to ignore the major marketing and public relations benefits that can be found online."
--Gary Vaynerchuk

P.S.
I bought his book, "Crush It!" It's small, simple, to-the-point, honest and a good read. Oh, and most importantly, the principals are very sound in today's electronic media environment. Proven by his personal results and by the many others who are successfully cashing in and living their passion. I recommend the read.
