> Lively, Google’s entry into three-dimensional virtual worlds, was publicly unveiled last July. Four months later, when the company decided to close it, only 10,000 people had logged into the service over the previous seven days. That was well below the targets set by Google’s quarterly project review process, and far behind Second Life from Linden Lab, which had about half a million users in a similar period.<p>Hmm. I'd be happy with that. I wonder how much it costs to run the service? I don't need to kill Second Life to be successful.
