Can you call Kirchner, make an appointment and relentlessly ask him your questions until he yields? I do that sometimes. If he's a professor somewhere, he'll have office hours. I consider professors to be public resources, like libraries.

Email and Comment Policy
Friends, we love thoughtful emails. Send 'em our way, and we'll respond in kind or on the blog.
Tell us!
We're reasonably good at answering emails, although no promises -- we get distracted. If you make us think about something in a new way, we might use some of your email in a new blog post, unless you tell us not to. It's really nice to know you're out there, and what you think.
