Social Media may well be the next great communication tool, but we should not get LOST on analyzing its penetration into markets, or measure the ROI looking for profit, gain, or some other kind of reward. We should learn to measure how much MANKIND has benefitted from Social Media as a tool. I think if we can as humanity look at this and point to moments where the medium impacted our lives (Arab Spring, Social Media for Social Change) then we can say with a resounding YES that this tool has Made a difference in the lives of humanity, and is the best thing in a generation!
