Not gurus, but better
Via my new friend Jonathan Ezor, there’s this, if you haven’t already got a got a copy: The Social Media Guidelines Ethics Guidelines of the Commercial and Litigation Section of the New York State Bar Association, dated June 2015.
I’d say take two, they’re small, but they’re not. They’re big. So that means be very afraid until you read them.
