Yuck
Ugh you've gone all Office 2013 / Win 8 with far too much unbroken WHITE and no shading / gradients / lines to separate the different sections of the page. My first thought was that the stylesheet had failed to download for some reason so I hit refresh before spotting the redesign story.
Could we please get an alternative theme with an off-white background or even an inverse theme with black background for those of us with a bit of Mogwai in our genes? The current one makes me want to put shades on.
