The interview format is a fascinating way to get a person's ideas. At one level, you can go on at greater length on a subject because someone asked; OTOH, you are at the mercy of another mind who wants to know only certain things about your thinking and opinions. Your views on education or numismatics or taxation, however much you might yearn to work them in, aren't going to be part of the program.
I have never interviewed anyone, but it might be fun. Think about whether you would like to be interviewed, and let me know. There's plenty of time.
