I've been playing with some mailing lists so that you can (hopefully) get this blog sent straight to your e-mail inbox. As this is pretty untested, there may still be some things to iron out, but I figure the best way to find out what they are is to let people sign up and send feedback.
There are two lists - both get the main posts as they're published, but the first also gets comments. Both should be extremely low-traffic, and they're both moderated so you won't get spam. To subscribe to either (don't subscribe to both, there's no point...), click the appropriate link and fill in your details.
And don't forget, you can still access posts via the XML feed.
