Another nifty article on Duplicate Content and SEO

This is another such article I've found on duplicate content, for those who have found themselves nailed by Google's duplicate content filter:

From the article, "This duplicate content that I’m reporting on should provide some good insights. Why? Because these sites aren’t attempting to spam the search engines. Instead, they’re just typical efforts by business units to brand something on the web with no consideration of the SEO consequences. You might also ask why, as someone involved with SEO, I’m not doing anything about it? Partly because the sites are eventually going to disappear as they are replaced by yet another recipe search and partly because examining the data should be quite educational."
