Depending on where the article resides, aside from driving human traffic the article provides a relevant 'topic' for the page. This adds muscle to the link to your site on that page, in addition to being anchor text link.
A great source to use. But again, it depends on where it is -- such as is it a site / page with enough
pr to make it worthwhile, and does the page automatically insert nofollow to external links, in which case it would only be for human traffic purposes.
