[Yoda]

Let me preface by saying, I am not one (good or otherwise).

But I occasionally seek them out. Here's what I think is most important (not necessarily in priority order):

1. Knowledge
2. Communication Skills
3. A PASSION for the craft
4. Genuine desire to help people

I would add a fifth characteristic: Ability to demonstrate.

Now, I invite each reader to add any additional characteristics they deem important. Once we have a complete list, maybe somebody (Patrick?!) could put up a Poll giving each characteristic a Priority Ranking so we can get a real feel for the "Characteristics Of The Great Instructor."
