I think that a high average time on page can flatten the affects of high exit or bounce rates.
So leave a bunch of browsers on an open page overnight to push up the numbers? Or make each link open into a new window?
I can see the theory being beguiling for e-commerce sites when the visitor is a shopper, but that is not the whole sum of internet activity.
It's still good to look at this statistic to weed out failing pages, but (as already mentioned above) many types of page are a success for the same analytics that make other types of page a failure.
