People on HN tend to be a bit picky about web design, but this site is absolutely terrible. In addition to the lack of a scrollbar it has navigation links that let you read _most_ of each section and has several different methods for scrolling in it (sometimes it gives you a big down arrow, sometimes you need to rely on the side bar, the side bar is apparently truncated for "ease of use"). Though, in firefox, arrow keys, space bar, home and end do work while pg up/dn randomly pan the map for some reason.
I am wondering if this was considered an interesting article or just a really good page to send front-end interviewees for as a "let's see how many terrible things you can find" game.
