One of my clients produces a couple multi-contributor blogs, and now wants to form a relationship with a major web publisher like Yahoo or MSN to post one of the contributor's blogs on the bigger site. Will having the blog on one or two of these sites have a negative or positive impact?

What do I do to make sure this is a link building win and not a duplicate content nightmare?
