I've been up up arround 2800 with an adult site lately. (not counting my old tgps from back in the days, I have no idea about that). Prolly arround 5000 right now.
One of our mainstream site is one of the top 500 most visited sites in canada thought
Another one is in the top 1000 (canada), and we have a bunch of them in the 2500 range (canada).
