This is a big day for me -- the publication date of my book "Parallel Play" (Doubleday) and my first attempt at writing a blog. I have a lot of friends who have been doing this for years -- the music critic Alex Ross at therestisnoise.com, the omniverous Terry Teachout at terryteachout.com, and my new friend, the brilliant and generous John Elder Robison at JohnRobison.com -- but I have always resisted.
