And in the death, as the last few corpses lay rotting on the slimy thoroughfare.......
 

While adding my pop under to unproductive sites I am also giving the once over to the sites. A quick tidy up to sites I have not looked at in months, or even years. I came across a blog I had originally set up in 2007, and while still active I traded links with other webmasters (this would have been 2007 or 2008, possibly 2009). I just went through it it remove the dead links. There were 33 websites on that list. In the past 6 to 8 years every single link has died. Not one of those 33 sites was still up and running!
