Reddit is an Internet firehose, a repository of the good, the bad, the silly and the shocking.
Online journalists should make it a habit to look at Reddit from time to time. Not only can it be a great way to promote work, but there always seems to be a good story waiting there. Sometimes it’s prominent, and sometimes it’s in an obscure corner of the site. The fact that the site’s slogan is “the front page of the Internet” is telling.
While Reddit still has a niche audience, the stories that are popular on Reddit probably have some potential to be popular elsewhere. If the story fits your site, you should consider writing something similar.
