This blog now has "Subscribe via Email". It is a feature offered through Feedburner. The idea is to allow you to receive posts from the blog in your in-box. Now, to be honest, I am not a big fan of getting blog posts via email. I would totally recommend that you use Google Reader for a lot of reasons, but if you happen to be someone who really just likes checking your email to get your information, this might be a good option.
It is really easy, just enter your email and click subscribe. You should get the next post sometime between 7pm and 9pm after it has been posted!
