The FORM method of building rapport.  Try to make at least five connection points to build rapport witth a stranger.   Using the FORM method is a good way to ask open ended questions.

F – Family –  Where did you grow up?

O – Occupation – Did you move there for work (instead of what do you do?)

R – Recreation – What do you do for fun?

M – Motivation – Why do you think you were drawn into podcasting?
