Second Life is celebrating it’s 10th birthday, an amazing milestone for anything software-based, particularly massive online virtual spaces.  In addition to lots of things happening in-world, they’ve posted some interesting numbers online about how well the system is holding up after 10 years.

“Second Life is a vibrant shared creative space, filled with the creativity and imaginations of its users,” said Rod Humble, CEO of Linden Lab. “It’s impressive for a user-created world to reach ten years of age and more impressive still for it to see a million monthly active users! As we celebrate this anniversary, Second Life has better performance and is easier to use than ever before, and our customers are making the inworld experience richer every day. We’re very proud to reach this milestone, and would like to say a big ‘thank you!’ to all of our friends around the world who have been a part of Second Life’s ten-year history and will be a part of its future.”
