Pardon my stupidity, but what does DU stand for?
You're not stupid. DU=Democrat Undergroud, which is a very vile, vulgar and popular website/forum that some call the Dem answer to FR. Trust me, they are exactly what we strive not to be. They are also irrelevant.
FR management doesn't want us linking to stories there. I concur.
FR management should drop its ban on links. These people are just so much fun to watch when they're having a bad hair day.
