Facebook+Defined

So what is facebook?

How do you explain facebook to someone who has never heard of it? How would you explain facebook to a your Grandmother?

How would you explain what facebook actually is to Mr. Holmes. This is the goal, since in order for him to be sold on the idea of trying to teach the teachers about facebook, then he must first understand what facebook is.
 * What does he already know about it?
 * How can we find this out?
 * Does he have a facebook Profile?
 * How does he feel about facebook?

The other side to look at is "what are the arguements peopel have against facebook" These are the potential barriers you will need to overcome in order to sway Mr. Holmes to your side. By investigating the common arguements both for an against you will be prepared for any opposition to the pitch.
