Punctuate This

I just finished reading Eats, Shoots & Leaves: The Zero Tolerance Approach to Punctuation by Lynne Truss. These two quotes might well sum up the thought and feeling of the book:

 “Proper punctuation is both the sign and the cause of clear thinking.”                                     

“The big final rule for the comma is one that you won’t find in any books by grammarians. It is quite easy to remember, however. The rule is: don’t use commas like a stupid person. I mean it.”
