In Virtual Worlds: A Business Guide, the newest O’Reilly Radar report, Ben Lorica, Roger Magoulas, and the O’Reilly Radar team get past the hype (and the anti-hype), detail what is happening in Second Life and other virtual worlds, and lay out what businesses need to do to succeed in these worlds, now and in the future. It examines business opportunities, evaluates what has been successful and what hasn’t, and what trends are starting to emerge.
