Again via Jaymin Carthage: an insightful article on "Debunking 5 business myths in Second Life", by James Wagner Au. He debunks myths on the size of SL and the size of the community, the economy, anarchism and sex in Second Life. Good reading stuff.
James, by the way, is the writer of a well known Second Life blog: New World Notes - a blog you should read if you want to stay up to date with all things SL. He's been covering SL for years.
