The first that I have found the time for is Dr. Adrian Warnock. You’re all familiar with Adrian as he is literally world-famous and a published author. He blogs here, and this discussion took place over e-mail due to my own inability to find time to get the technology worked out in a suitable manner. If I am totally honest, I believe that the written exchange will be far more useful in this case so that it’s obvious to the reader whether and to what extend the questions involved are actually answered. The format for the discussion was this: each person asked the other five questions and had a final opportunity to respond to the replies; we expanded that after the first round of answers to provide for some follow-up or explanation. If it looks like the person asking questions is trying to give you whiplash, it’s because the discussion moved, by design, to the next question. Adrian has asked me to improve the format to show where the “next question” begins, and I have made an effort to do that.
