I have a related question:

Suppose you write an original article and put it on your site, and then a few months later post a complete exact duplicate copy of it on a dozen other sites. How much risk are you taking that Google will eventually mis-identify one of these copies as being the original and give it priority in the rankings for the main keywords?
