Kilgore, a college student who had recently returned from military service in Iraq, had been challenging aspects of his upbringing, and his father (a fundamentalist pastor) concluded that reading Richard Dawkins' The God Delusion inspired Jesse to kill himself. The Disco. Inst. decided that the best thing to do was to glom onto that father's grief in order to drum up end-of-year donation. Given that the suicide rate for Iraq veterans keeps rising, I'd look past Jesse's...

A couple months ago I became a subscriber to Very Short List, an email list that sends you just ONE web link a day, 5 days a week, as a way of clueing you in to something that is both good and overlooked: Might be a movie, a web site, a blog, a book. I've now become a (modestly) paid "advisor" to a new VSL email sub-offering, VSL Science, a science-only version of the same daily email. The Shirky talk on Gin, Television, and Cognitive Surplus in my previous post is today's VSL Science offering, and it was something I managed to stumble over and offer up in my advisor role. It's a fun list to get, so you might want to subscribe (free) and see if you like it. In any case, from time to time I'll include...
