When business owners ask me, "what's the ROI of social media?" it's often a not-so-subtle hint that they believe that social media marketing is a big, fat waste of time and money. So, sometimes I respond (only half joking) with, "Do you give a sh*t about your customers? Yeah, of course you do. Well, what type of ROI did it get you last month?"
Some people still don't get it.
