CEO Blogger Alert.
I met a CEO with a blog last night. Tom Glocer CEO of Reuters sees it as primarily an internal mechanism, but agreed that it has external ramifications - and that he needs to blog more frequently. But it's a start - one to which he's committed (regardless of the risk-averse concerns of some of his advisers) and if it were better known outside of Reuters, I imagine the external benefits might become more apparent to him.
Like other commentaters, I have never really got Second Life and some of the "virtual laboratory" claims made of it, as I have written here and here, but this is an approach that seems more liable to generate real insights.
Bonus link: This television report on the religious nature of the immersion of the virtual world aired a few weeks ago. It's the one labelled "virtual death".
