Ezine Articles is now looked at as a trashy, spammy website, and the links from the "author bio" area hold no value. I have seen first hand, these links destroy some of my clients rankings. After I emailed Ezine and had them remove all the articles for that client, they ranked well again. This is an example of how lame links from article directories are. They offer "platinum" and "diamond" statuses to entice the author to write more articles for status points. This is all propaganda, and should be ignored. I would not waste any time in the ezinearticles.com domain. Just an SEO professionals opinion though.
