What's the true cost of photocopy paper?

I wrote this piece on the environmentalist blog

http://world.the-environmentalist.org/2009/06/whats-true-cost-of-photocopy-paper.html

but things get confusing now because this blog is personal, not professional. However, I had to use the same log in and email as a contributor and writer for them as I couldn't be bothered setting up a new one. Perhaps silly of me.

So - I've had to untick this blog from my profile so people can't see it.

Ah - the age of google and gmail - so much for personal, professional divide.
