To me the interesting part of this was how social media is sometimes absolutely amazing. Woz idly poses a question about the fuses in his car and has an engineer from the manufacturer write a detailed response in short order. That is incredible.
That's less social media and more Woz asking a question.
Or rather, this is the internet at work, not social media. The only thing social media has done is reduce the time between question and answer. And that's impressive, but it's not the fundamental shift the internet itself was.
