There have been some interesting comments in SearchEngineWatch about industry-wide approaches to fighting click fraud, the likes of which I'd mentioned to people like Barry and Phil long ago when I first became aware of what people were trying to do with the web server logs.
In other news, I have been reading Moneyball and enjoying it. Stay tuned for a post on it. (Interestingly enough, it ties into some other things I've been discussing lately.)
