[ExI] Mining the Sky SL Talk I gave today

[samantha]

BTW, this talk was done for a group called The Fulfillment that I 
started a while back in Second Life.  It is focused on what can be done 
in the near term to actualize a highly positive future taking humanity 
up to and through the technological singularity.  We meet in SL at 1100 
SLT (Pacific Time) every Saturday at 
http://maps.secondlife.com/secondlife/Transvision%20Nexus/40/86/41. 
Please drop by if you are in world.

Now that I have a bit more time, I am building a RW presence for the 
group.  We have a fairly new group page on Facebook, ning presence (not 
very fond of them so not much maintained) and I am working on a website. 
   It is likely that a meetup group (Bay Area) will follow soon.
