The article has been updated to include this:
[UPDATE: Someone has just pointed out to me that Brett Walton has accused me of reprinting a 'confidential email conversation' for this article. In the course of my discussion with Brett, I specifically asked him if our emails were on the record. He replied: "I have no issues reproducing the discussion - needs a tidy up of course." As far as I'm concerned, issues like this are symptomatic of why VGChartz cannot be trusted.]
hmmm...yeah...best not to publicly complain.
