I just saw her two weeks ago taping her interview for Overheard with Evan Smith. She was in top notch form and had the audience at the edge of our seats and in tears at moments. I am glad I got to go -- but I am sad the world lost Jane.
I agree - as someone without kids in a neighborhood full of kids. In my decade of living in the burbs, I have not seen 2 children playing/going somewhere/interacting without an adult around once. I think most parents don't leave their children unsupervised AND there is a very easy alternative (videogames, internet, netflix, etc - as you mentioned).
