Are you being Duped by the Duplicate content theory and other SEO theories?
Go to any article directory, take the title of the article and paste it in a search bar. See how many results you get. !!!! If google indexex it 200 times i am sure that they are not worried about it. Read the article and it will help you understand.
There is a lot of mis-information on the net about seo
Hope this helps.
