I'm really enjoying the Boellstorff book 'Coming of Age in Second Life'. I thought that this was right on the button: 'Second Life culture is profoundly human. It is not only that virtual worlds borrow assumptions from real life; virtual worlds show us how, under our very noses, our "real" lives have been "virtual" all along. It is in being virtual that we are human: since it is human "nature" to experience life through the prism of culture, human being has always been virtual being. Culture is our "killer app": we are virtually human.' (Boellstorff, 2008). And that's only p.5...can't wait for the rest!
