A couple of weeks ago the Washington and Lee School of Law hosted a symposium on the social and legal implications of the recent emergence of virtual worlds for kids, entitled Protecting Virtual Playgrounds: Children, Law, and Play Online. The organizers have now posted video (and audio) streams of all of the symposium presentations, including a panel on play featuring Dorothy Singer and Greg Lastowka, and a keynote address by Edward Castronova. Very awesome of them to make this publicly available, as it sounds like it was quite a fruitful event for those involved. It's not often that economists, law scholars, designers and psychologists get together to talk shop.
I've got to say though I'm pretty disturbed that I didn't find a single media/communications scholar on the speakers list. Hopefully there were at least a few in attendance, but even so, it's quite an oversight considering how much of the work (past and present) on kids' mediated play, digital games, etc. has come out of this discipline.
