Second Life millionaire 'Anshe Chung' interviewed

Some of the world's wealthiest people have made their fortunes in real estate. People will always need land and there's only so much of it to be had, the prevailing wisdom goes.

So it can be hard to fathom how a person could amass wealth by selling virtual real estate inside a man-made virtual world, where the digital landscape is effectively limitless - when you start running out of space, you can just create more.

But Chinese businesswoman Ailin Graef says she has become a real-life millionaire with a $10 US investment as land baroness Anshe Chung, her identity in the online world Second Life.

CNET News.com's Daniel Terdiman interviewed Graef about her business and her views on China, censorship and the future of virtual worlds in a two-part interview.
