"Stricchiola harshly criticizes Google, saying the firm typically will not divulge much information to advertisers about the nature or scope of click fraud on their Web sites. Google defends the practice, saying it does not want to provide a road map for those with bad intentions.
Stricchiola says Yahoo takes a more open approach by sharing data with advertisers who complain about click fraud, enabling greater collaboration to minimize the problem."
I should think that Google, with its engineering and open source expertise, would realize that the "road map" is already quite well understood among the Internet technical community (including the fraudsters, who can study the protocols just as easily as anyone else).
Google and Yahoo are reporting earnings this week. It should be interesting to see how they respond to the questions about click fraud.
In other news, I'm still enjoying Moneyball. I just finished the chapter on Bill James, who pioneered sabermetrics, the in-depth statistical analysis of baseball we have today. I remember back when I was working for SRI in the mid-1980s, I had some friends who got involved in rotisserie leagues. I thought it was interesting but didn't have time to participate. Internet historians may find some discussion of early sabermetrics in usenet baseball newsgroups via Google Groups.
I'm still keeping up with my piano practicing, but haven't had much time to study French.
