What I find most mysterious are the article sources (okay, not that mysterious).

I've never visited smithsonianmag.com in my life. Yet, there are four articles from that site on the front page right now.

Something isn't working...

Someone posts an interesting article from a source. 10,000 people visit that source. Some of them noodle around and find other interesting articles and submit links to them.

It's a problem if the submitted articles are low quality.
