To help some of you get started, I’d like to give you some information that makes following a blog a little easier. Below are three ways to follow a blog, read through, and see which one is the best for you.
1. Go to the Website – If you’re reading this page, then you probably know how to follow a blog by going directly to the website. In this case (kateandryan.wordpress.com)
2. Receive Blog Posts via Email – If you prefer, you can have blog posts emailed directly to you. I’ve added the Feedburner service to this blog which will email new posts once a day, when there are new posts to email. Just Click on the link under “Subscribe by Email” to the right. Of course, you can unsubscribe at any time.
3. Via RSS feed in an RSS Feed Reader – This option is the most advanced, but it can be very useful for aggregating information from across the internet that you like to read on a regular basis.
If you are ready to dive in, I recommend Google Reader. This will get you started with adding Kate and Ryan in Italia to your very own Google Reader: 
Otherwise, if you want to learn more, RSS In Plain English is a very good introductory video that explains what RSS is, what a reader is, how to get started, and why you should care.
