Ya, I realize that, which is why I said it is skewed, especially when it comes to topics. Within a topic however (in this case porn sites in general), you could expect people with the toolbar installed to visit a variety of sites in that genre and it would reflect what they are doing over time. It wont give you absolute numbers (like actual subscriptions or anything like that) but it will give you an order of magnitude of general interest and how that is evolving over time.
