Recommended Reading: ‘The Entrepreneur’s Guide to Second Life’

Technology writer and acquaintance Daniel Terdiman has authored an indispensable book for those wishing to plan, launch, and maintain their own Second Life business schemes. Entitled The Entrepreneur's Guide to Second Life, it stands as a comprehensive examination of Second Life business basics, largely based on the input of selected residents of the virtual world. The Guide speaks in a language even Second Life newbies can understand, and offers practical solutions to common commerce challenges. Thankfully, Daniel hasn't penned a "get rich quick" manuscript, but rather offers a balanced look at what goes in to making real money from in-world entrepreneurship--in short, a hell of a lot of work.

It was only a year ago that a reported 3,000 SL residents were earning at least $20k USD annually in-world. Since then, Second Life's population has skyrocketed, so it's probable a lot more people are making decent money off the virtual world. Not me, though.
