Martin,

Your experience of the usage of this term is of course useful and adds to the overall picture in a helpful way.

My experience is different and hopefully provides you with a broader view of how the term is used.

The old Indian story of the Elephant being examined and described to the villagers of a blind community by three blind men teaches us to listen to the experience of others and add it to our own experience and not to rely solely on how we have perceived things.

In the above story, the three blind men have a fight - one of them says it is definitely like a snake, the next says it is definitely like a tree stump, the last refutes such absurd statements and says it is like a rope with a fly whisk on the end.

None are wrong, and though their experiences don't seem compatible, they are.
