Adding email subscription

While making a variety of site design changes I’ve given in and decided to start offering e-mail subscription to this blog. While I wouldn’t encourage anyone to use email (RSS is essential) if that’s what you’d like, it’s now available. It’s also a chance to check out Feedburner’s own new e-mail service, which looks better than their partner services they’ve had for awhile. We’ll see how many subscriptions it gets!
