I've been continuing to think about this topic, and I've realized there's at least one more parallel to make:
The converted - aka us (I'm including you because you're reading this blog) - spend too much time preaching to the choir - aka the people who've already drunk the kool-aid - and ignoring the godless heathen infidels - aka the skeptics.
We need to stop turning our backs on skeptics with a dismissive: "Well, they just don't get it, so to hell with them."
Do you truly believe that social media is transformative? If it's really that important, you need to HELP them get it.
