Virtual money economics author to sell book for virtual money

In a tradition set by Cory Doctorow and Lawrence Lessig, this Thursday technology journalist Julian Dibbell will appear in Second Life as an avatar named "Julian Dibbell" to autograph copies of *Play Money*, his latest book about making a real living by harvesting gold in Ultima Online.

Going one more meta step, Julian is also *selling* virtual copies of *Play Money* for Linden Dollars, the official currency of the online world. In other words: on behalf of Julian Dibbell, "Julian Dibbell" is selling *Play Money* for play money.
