I just don't know what to say about this. Yes, the idea of a virtual world is super interesting and very important. This particular virtual world, hmm, not sure. Hype around second life, fueled by companies eager to appear hip, has the potential to crush the idea before it gets traction. Every time someone reads about this and thinks it's mainstream, logs on and sees what is there (and let me tell you, nothing against realtors, but having the ability to work with a realtor in second life is really not much of a draw), another person leaves, not to come back.
For a far better look at a virtual world, teeming with life and PEOPLE, check out this Fortune article. It is a much better proof of concept and experience.
