Social media practitioners must understand what not to do in the space, as the grassroots are extraordinarily unforgiving and interconnected. Don't be a weed. To wit, I received a message from a friend on Facebook, and immediately it struck me that he was shooting himself in the social media foot with an uzi. The message which I received was sent to 18 persons whose first name begins with the letter R. One can only assume that this instance of his message recurred many times, hence the uzi. It comes across as spam, however well-targeted it might be. It is a formula for failure.
