Ok, it really is a good book, accessible to any programmer, even if you don't already know Python. I find natural language to be fascinating and this book is thought provoking. It covers symbolic logic, the lambda calculus, statistical techniques of speech recognition, and offers very practical and clear Python code snippets to show how to use the NLTK. I was too lazy to write a review but I did record my thoughts in the podcast at href="http://www.awaretek.com/python
