I was answering some questions for a journalism student in the UK about how social media has emerged as a major component of our day-to-day lives when a quote by a smarter man than me (yes, there are billions, but one in particular stood out) came to mind. It got me thinking (scary, I know) about what really has happened over the past 4 or 5 years that took an obscure niche of the Internet and turned it so mainstream.
