Many people subscribe to blogs in feed readers, where they can stay up to date with everything in one place. But there are also many people who don't do that.
For those who use a reader, you can easily subscribe by clicking on the RSS icon or on this link.
If you don't use a reader, there is still a very easy way for you to keep up with this blog. You can subscribe by email. Just click that link to sign up. Then, each morning the posts from the previous day will be delivered right to your inbox.
And if you don't use an RSS reader but want to get started with one, Abraham Piper has a very helpful post on how to do that called What is RSS? A Step-by-Step Guide to Google Reader. He writes: "If you follow these instructions, you will be subscribed to your favorite sites and already saving time by the end of this article."
