I'm afraid I cant give you the intelligent comentary from a statistician you are looking for (stats was a minor part of my degree). However, I would have to say that quotes like

"Dean observes that "such large changes will eventually occur by chance, of course, but this particular change happened during an unprecedented event, suggesting that this `spike' and `rebound' were not coincidental.""

do not fill me with confidence. I would be interested to see their data in "quiet" periods and see whether the same fluctuations occur from time to time. I looked over their website a little when this was posted a couple of months ago - there is such a lot of data to wade through though.

It does seem like they are also attempting to form a hypothesis and decide on testing techniques ahead of time - this would have much more meaning to me.
