Trendwatching.com has an entire digest dedicated to the virtual world and some of the upcoming commercial applications. I liked the article form a 'hey that is neat' perspective but what they did not address was how the residents feel about the incursion of advertisements and branding into their worlds. I look to the real world where residents are fighting the development of Walmarts. All I can say is that when entering a community it is wise to relay understand its residents before making investments. I love that they mentioned the Second Life Relay!
