Seeing as the deadline is fast approaching for the click-fraud case, I wonder if anyone else has views on the size of the double-click issue that was resolved in March 2005 (i.e. charging twice for a double click on an ad).

In Tuzhilin's report [googleblog.blogspot.com], he states (p30):

It turned out that the change in the doubleclick policy (i.e., not to charge advertisers for the immediate second click in a doubleclick) had non-trivial financial implications for Google. Being a publicly traded company at that time, this change would have had a noticeable effect on Google’s total revenues with corresponding implications for the financial performance of the company.

If the management of the company had 'legitimate concerns' (p.31), I sincerely doubt that the impact of only charging for the first click was only worth $90m looking back to 2002.

Is this a valid reason alone for rejecting the class action, and do you think that the number of people that will/have rejected the case will prove sufficient to launch a second one?
