Interesting. Description of a teacher's experimental forays into Second Life. "I was able to talk with other educators and bounce ideas off of them... all of this could be accomplished in an educational centered chat room, but somehow this was different." Great, right? Well, there's this: "I still probably won't make it back into Second Life anytime soon because I don't have the real need right now." And I worry about this, from a CNN article: "It's the ability to use Second Life as a platform for a whole new Net - this one in 3-D and even more social than the original - with huge opportunities to sell products and services." And more, as noted by PacRimX, "Linden hopes to control the standards for virtual worlds so that they become the equivalent of the HTTP and HTML standards that define the web." We had a standard, remember? VRML. What was wrong with it? Nobody owned it. We need to be careful, as I argued in 2000, to preserve our public spaces.
