FULL DISCLOSURE: I adore this site. I love the design and the user interface. The concept and the content are top notch. (Please don't let Yahoo! buy it and ruin it like they did Flickr. Hold out for a chunk of Google's money.)
The thing that gets to me is the color scheme. Is the person in charge of the page's palette colorblind? The worst is the Talk section, really. As you scroll down the page the colors look like an office, circa 1992, when all computers and peripherals were putty, gray, taupe, or sand. Then there is that papaya-colored stripe at the top, it clashes and isn't the same color value
But, I may be the only one that feels this way. What do the rest of you think about the color scheme?
