Reader macros are perhaps not as famous as ordinary macros. While macros are a great way to create your own DSL, reader macros provide even greater flexibility by allowing you to create entirely new syntax on top of Lisp.
Paul Graham explains them very well in [On Lisp][] (Chapter 17, Read-Macros):
The three big moments in a Lisp expression's life are read-time, compile-time, and runtime. Functions are in control at runtime. Macros give us a chance to perform transformations on programs at compile-time. ...read-macros... do their work at read-time.

NOTE: This is a question I found on StackOverflow which I’ve archived here, because the answer is so effing phenomenal.
If you are not into long explanations, see [Paolo Bergantino’s answer][2].

; The main reason for this guide is because there are very few examples that | |
; explain how to get started with socket programming with Common Lisp that I | |
; could understand. After spending a day trying, I finally came up with a small | |
; bit of code that makes it easy to understand the basics. I've written this | |
; primarily for myself, but should help others get started as well. | |
; As usual, we will use quicklisp to load usocket. |
