If you would like to receive updates when new posts are added there are two quick and easy ways to do so.
The first is to subscribe to the feed (a list of new posts) through a feed reader. Just add my feed address to your favorite reader (http://blog.brentknowles.com/feed/). The reader I use is Google Reader.
You can also subscribe via e-mail.
To sign up for an email subscription just scroll down a bit and you will see the sign-in box.
