Assigning Twitter and other social media platforms to the summer intern who is presumably an "expert" in the field due in large part to their age intuitively makes sense. But think about it: Would you give your teenage son or daughter not just keys to the car when they have never driven a mile in their lives, but park them at the helm of a 747 and expect them to fly?
Social media and small business were made for each other. These companies have little or no marketing staff. Social media offers the opportunity to reach millions of potential consumers through virtual channels. The cost savings are significant, and the reach is amplified, but business owners better bring their "A" game.
