The new York Times writes about Second Life:
In a world called Second Life, especially (where the virtual Hawaii described above can be found), so many people visit that profitable businesses have sprung up that earn their proprietors real money, not just virtual currency – in fact, a handful of people earn six-figure incomes there. There are discos, casinos and other sites that can be rented for private parties or even for the virtual weddings many people hold.
Practically everything in Second Life’s world was created by its residents, who come from 80 countries around the (real) world. Linden Lab, the company that runs Second Life’s world, provides a set of content-creation tools that its members have used to create everything from nightclubs and movie theaters to coffee shops and bars to airships, automobiles and clothing stores, a few museums and one or two libraries and nature preserves.
The company itself creates practically none of the buildings and other sites in Second Life, but provides only the rolling landscape on which the more ambitious of its members build.
