The reddit Front Page is Not a Meritocracy

I was pleasantly surprised when somebody shared my traveling salesman animation to reddit and the post made it all the way to reddit's default front page (i.e. the top 25). The gif racked up over 1.3 million pageviews on Imgur, a testament to reddit's traffic-generating prowess. Before the post made it to the front page, though, it was...
