The real advantage to building a few back links to your EZA article IMO is that it will help to keep the article indexed at the SEs. Submitted articles (like blog post, forum threads, etc.) often get deindexed once they fall off of the home page, recent posts/category/thread/articles pages, etc. Once the page is only accessible from the EZA archives, they often get deindexed if they have not acquired some back links.
