This is something that has definitely come to our attention.
The funny part is that the site design has been pretty much the same all winter long, but now with spring coming about its when everyone starts to notice all the things wrong.
We're very concious about how currently the site is kind of a mismash of various ideas, and that we have upped the ante with the ad serving. This all leads to the fact that it needs to be cleaned up a TON.
As we do every year, the summertime will be when we begin the overhaul of NS. We're going to address all the issues affecting the site, and really take a long look at how everything is looking. I know that cko (who does all web design) is REALLY excited to sort out the mess that this site has become.
So know that we're aware, and we want to make this into the best site in the world, and that we are right now working to make that happen.
