Alice, over at Kotaku, has a post up looking at what Second Life means to the Web 2.0 crowd. Cory Ondrejka gave a presentation at the O'Reilly Emerging Technology Conference about what 2L is about, and dropped some interesting statistics on the audience. From the article: "Here's Cory's killer factoid, just announced here: Over 70% of Second Life residents have created an artifact - from scratch - in this past week. That's one crazy level of output. To give you a bit of perspective, that's approximately 23,000 human hours of play-work per day. Cory points out that this would cost Linden Labs over $400m a year to produce centrally, clearly not a viable business prospect. "
