Early spring cleaning

I’ve made a couple of minor changes to the site. First, you’ll notice that the dorky-looking Amazon blob is gone from the right side bar. No one was clicking on it anyway. Second, there’s a new form for signing up for the goodies mailing list– I’ve moved from pairlist to Topica’s paid publishing service, which means that all y’all will finally have a real interface for subscribing and unsubscribing.
