Esther Dyson started a blog named Release 4.0.   Welcome to Blogland, Esther!  I am not impressed by amount of intelligence a person has, having plenty of it myself.  What I am impressed by is the shape and movement of intelligence a person has.  Esther's intelligence feels razor-like and moves like a chef, using precision and timing to prepare a good meal.  I was impressed with the way she cooked NetBeans.  In her second post, she talks about Applied Semantic, a recent Google purchase, she provides behind the scene glimpses.  Her blog is now on my daily reading list.
