Not. But the Times of London claims that Second Life is "the interactive online game with nearly 8m players worldwide", proving once again that just plain lying is often the best marketing strategy. By counting everybody who ever opened a free account for Second Life for 5 minutes, Linden Labs managed to fool the reporters.
The truth about Second Life can easily be found on their own website, which has stats on players and the virtual economy. So how high do you think the number of "premium residents" aka paying subscribers is? 75,000, a factor 100 short of "nearly 8m".
