So I've had a couple of people say that they haven't commented because you have to sign in with Google. Silly persons! It's painless, really! You don't have to get a new email account or start a blog or sell apples on streetcorners. It's no more complicated than the sign up I had to do so I can read the New York Times online. (Less so probably, because I can never remember the name I signed up under for the NYT and I always have to go look it up.)
So sign up, drop a comment- don't be shy!
