If anyone is tempted to click through to the article, be warned that its just a rant about how Second Life's engine sucks. It doesn't analyse anything about the world's systems at all, or even whether it's a success/failure at what it set out to do.
Yes, but the title is enough for people to agree before clicking. Good choice, I guess.
Myself I was also expecting a more detailed article about the economy, the communities... And it's just a basic rant about the time it takes to load items.
