The font/color for visited links both in comments and questions/answers is barely distinguishable from normal text: 

It's especially bad for commments: 

- Unvisited link:

- Visited link

      [![enter image description here][2]][2]


but questions/answers aren't much better: 

   
- Unvisited link: 

   [![enter image description here][3]][3]

- Visited link: 

  [![enter image description here][4]][4]

This should be changed.
