I often wonder if we in the social media punditry business are all just talking in one giant echo chamber. We tweet at each other all day and publish blog posts just like this one, hoping to get some accolades (in the form of tweets, Facebook posts or comments) from our co-pundits. Most of us read voraciously, though often only within our own ecosystem, rarely venturing out into other spheres. I know I often fall party to this behavior, removing people from my Twitter stream when they venture too far afield (no, I really don’t want to know about your new yoga obsession), and ruthlessly slashing the titles in my blog reader from time-to-time so that I don’t waste a precious minute reading about something that’s not in my daily purview, like that silly stuff, economics, or some such.
