Virtual Worlds Users Exceed 1 Billion

In Readwriteweb: A remarkable milestone. Some interesting breakdowns of the data as well. I watched the early development of places like Second Life. What continues to disappoint me is that nearly all of this participation is gaming and not a serious attempt to provide value. I saw some early attempts, particularly from IBM, to make these spaces into a real work environment. Where did that go? OK, its fine to provide entertainment, but if it is just a billion people not doing real work? It is not sustainable.
