Remember Second Life?

  Yesterday it was a flippant aside; today I really mean it: what ever happened to Second Life?  You remember Second Life, yes?  As Wiki says, it's a "virtual world" where,

Residents can explore, meet other residents, socialize, participate in individual and group activities, and create and trade virtual property and services with one another, or travel throughout the world (which residents refer to as "the grid").

A couple of years back, for all the buzz you might have thought Second Life was on the verge of becoming our First Life, taking over our brains, our energy, and our, you know, everything.  And then--what?  There's still a website, of course, but right now it is still showcasing the news that "Valentine's Day is Monday, Feb. 14."   Thanks, we know that and we wonder where is the Avatar who should be updating that.  Could it be that he is over at Facebook playing Oregon Trail?  Meanwhile the Wiki reports that the sponsoring company closed half of it office last year, and is down to 245 employees--Facebook, for comparison,  declares it has over 2,000.  Could we be hurtling towards history's first-ever virtual Chapter 11?
