Well, the site is called "Ezine Articles" so this implies that the articles are supposed to be distributed to eZines which are emailed Newsletters.
I think the concept is that writers submit their articles to this service and the articles get picked up by newsletter publishers to bolster their content and provide extra value to the readers of the newsletter.
The article writer then gets a chance for people that read and like their article to go and check out their website.
But maybe this concept became skewed in favor of SEO and making money from Adsense?
