HN gets about 60k unique visitors on weekdays. We used to have about 750k pageviews on weekdays, but I just cracked down on crawlers that were killing performance, and the number is closer to 650k now. I've heard from several people that HN is a source of referral traffic out of proportion to its size, presumably because its concentration means more articles are interesting to more readers. But it would have to be a traffic source way out of proportion to its size to get the kind of numbers they're quoting in this study.
