... I expect that the value of this post
    will lie in the commentary.

I'll return in a few days and see. I don't expect that to be the case, but I hope my expectations are confounded, and that there really is something interesting emerge. My question was sincere, and the fact that genuine enquiries such as this get downvoted further suggests to me that it's simply car-crash voyeurism and a form of schadenfreude.

If only we could define all these terms I'd be willing to stake money, but, as I say, I'll come back later and hope to find a decent, enlightening and constructive commentary.
