That's right, not about alternate reality. In it. Charles Nesson--the professor whose preclass pot-smoking habits were an object of national speculation in 2002--created a virtual persona, or "avatar," on the virtual reality website Second Life. Now he's having his "avatar" teach a class, "CyberOne: Law in the Court of Public Opinion"--the very same course he teaches to actual Harvard law school students, the Crimson reports. The class, which covers the law in cyberspace, is filled to capacity--perhaps owing to this introductory tape, on YouTube courtesy of IvyGate.
