Freelance Writer becomes Gold Farmer

GamePolitics posted a review of a book called Play Money: Or, How I Quit My Day Job and Made Millions Trading Virtual Loot. From their review:

he sought to prove that he could make more money in one year trading items from massively multiplayer online games (MMO's) than he had ever earned as a freelance writer.

Considering you can easily be a freelance writer and make $0 in a year, this is a highly suspect goal. Though it does give me an idea for a book!
