Courtesy Louis Platini's Metaverse Business, a Second Life/OpenSim analytics company that gathers publicly accessible in-world data for its clients, here's the top 50 most popular sims in Second Life for December 2011, listed according their average visitor count, the unique visitor range at any given period, and the sim's rank the previous month.
