Interesting post on REST

I just stumbled on this interesting post titled 'How I explained REST to my wife' by Ryan Tomayko. The best past about the post is that Ryan explains the whole concept of Internet & its related technology in its latest avatar (read SOA) in a conversational manner. He covers the concepts of internet in the past & its limitations, their protocols and how things have changed over the passage of time in a layman's terms & drives the picture of SOA or to be more precise REST in a simple manner.
