Queue my usual harangue:

Articles do MUCH MUCH better on reddit if, when posted, a brief description of 
the content of the article is also posted. Like what sarn posted here.

Not doing so seriously blunts the value. People need a reason to click on the 
article. It's why when you google something, you don't just get a list of links. 
You get a blurb with each link.
