Usability wasn't really what I had on my mind at that time. I just 
wanted to explore the idea to make use of the logs.

I think we could provide the logs in an anonymized form, ie replace the 
IP addresses and uids by some unique string that can't be tracked back 
to the user, to people who'd be willing to look into this.

Yeah, might be difficult to spot. Especially with people who use tabbed 
browsing and who might open a series of tabs from the same start page.

How would you define a succes reate of searches? We log search requests too.
