It will live somewhere on opera.com (I work in QA at Opera)

I found this data very interesting. But it might not intersect that well 
with what I was looking at...actually, I didn't respect robots.txt in my 
crawling. [maybe for that reason, the two studies complement each other 
=)] Not consulting robots.txt was an omission on my part at first, but 
when I considered the issue, I decided to keep using the process I 
already had in place.

- The entire set of URLs was randomized, so the chance of violating a 
robots.txt crawl delay was pretty low.

- The crawl used the DMoz URL set, with domain limiting (a cap of 30 
URLs per domain). This would avoid hammering any server.

I'd love to discuss more about any potential cross-talk between these 
studies though.
