Hello everybody,
I just read this interesting article and thought I would share it with you.
http://www.seomoz.org/blog/the-illustrated-guide-to-duplicate-content-in-the-search-engines
It gives you a visual diagram on how Google determines if you the content on your site is duplicate or not. It is one of the most challenging things to do when you're thinking of writing original content, but there are ways around it. So read it and try to understand how Google looks at it. It might give you some new ideas.
Good luck.
