Hi Tom,
Just spent an hour or so reading through this thread because I'm working on an osC site and I am planning on using this contrib.
I'm amazed at the quality of the contrib and support. Just wanted to say that in all of my sites, the referrer logs paint a much different picture than the google "link:" query.
I'd imagine if you looked in your logs you'd find a lot of linking sites. I'm planning on trying out the (relatively) new "Google Analytics" service as it looks like a great analysis service. If you haven't seen it you can read more about it here. Looks really nice, and it's *free*.
Cheers,
Chris
