Ok, it's late so I will make it quick.
US SWAT killed a young because they've "facebooked" him before serving a warrant. All story here.
The facebook picture of the young guy showed him armed with a shotgun ... so they came in with the Swat and the worst happened !
We had social networks for the dead, we know have the first dead by social network.
Second is the fact that an average Second life avatar is consumming more electricity than a Brazilian.
Note that Nicholas also has doubt about the SL model.
So all in one, we are on the verge of so many new problems that we will need real life improvement!
A reboot or an upgrage is quickly needed !
