Thanks for your thoughts Edward! I will possibly go into a more deeper explanation in a longer article I hope to write.

It has been great to hear everyone's views on this short article. It's intention was to bring about thought and spark some new ideas which I think it has. And I am happy with all the responses so far.

Thanks for all your thoughts and it would be great to hear what you think in the next one, so I may tag you in it.

I would like to address some of your comments made here also, so thanks for taking the time out to comment. :)
