There have been those who have asked concerning email updates instead of using an RSS reader. I will be adding that feature shortly so keep checking back.
In the meantime, you might want to consider using a RSS service like feed wrangler. This service will allow you to access and sync all your feeds across all your devices. They even have their own podcast and RSS reader apps.
You can also leave a comment here if there are other features or ease of use that you would recommend to add to the site. I hope to have the email signup by the end of this week.
UPDATE (2014-02-27): You can subscribe by going to the bottom of this page and entering your email address. You will be asked to verify your subscription. Then you will be sent an email to confirm.
