As I approach my first anniversary as a SAGG poster I asked myself a few questions about the experience.

1. Are you likely to get a straight answer to a question?
Unlikely.

2. Will you get a lively discussion with lots of food for thought?
Usually.

3. Will it be fun?
You bet it will.

As far as this topic is concerned, I'm not sure that I am any further forward than I was at the start. Maybe there's more to come.

There never was nothing.
