Are social networking sites good for business?

I often encounter this type of question with regards to education: Are social networking sites good for business? The question assumes that SNS possess some intrinsic value in themselves. Simply put, social networking services are good for communicating and connecting with others. If that’s your aim - in education, business, or whatever - then, yes, these tools can be useful. Outside of an aim, in keeping with Gibson’s concept of the need of an agent to perceive affordances or action potential of a tool, SNS have no value.
