At last count, there were 565 people subscribed to this blog via email. This service was provided by FeedBurner, a Google company. There used to be a place on the right side of my Home page where you could subscribe. However, Google has stopped development on Feedburner and rumours are that the service will shut down on 20 October 2012, so I have removed that option. As of yesterday, the Feedburner email subscription service was still working. I am not sure how much longer it will be up, given that Feedburner tells me I have zero subscribers.
I have recently added a subscription notice widget powered by WebFish, but it only gives you the link to the new post, not the entire post in the email itself. At this time, this is all I have found that is available. If you would like to continue to receive updates by email, I would suggest subscribing to the new notification system located on the right column of the Home page.
