What kind of blog is this?

Recently I've noticed that authors have been making blogs about their books. It looks like a good way to turn a protracted monologue (a book) into a dialogue, or even a small forum. It may also help the book find more of its intended readers. If this blog can serve these purposes, it will have been worthwhile. So I will share excerpts from and commentary about my book, Fighting Traffic: The Dawn of the Motor Age in the American City (MIT Press, 2008).

To most bloggers, a blog is an opportunity to shout into a magic valley that can generate echoes that are greater, not less, than than the original shout. So I will intersperse posts about Fighting Traffic with comments by its author—whatever might generate echoes of interest.
