It looks terrible? Really? It's an uncluttered layout with the tl;dr description of what it actually is prominently on the front page, and with easy-to-find navigation links to everything else above --- and if you notice, the informational links are on the left, and the actionable links are on the right.
To me, it's exactly what I want out of a product's website, and I wish more looked like it!
It's utilitarian to the max in that it cares little for graphical design. The layout is fairly functional, though I did initially think the menu links at the top were disabled given that the links below were classic blue underline.
I can easily see why someone would call that terrible; it looks like a time-warp back to the mid-90s when Netscape rendered the default HTML background as grey before everyone eventually standardized on a white background. You actually have to go out of your way to make the logo and menu medium grey on light grey when the same amount of effort could have been put towards a cleaner, more modern, and higher contrast look without changing the utilitarian layout.
I like. It has easy to glean information and no extraneous clutter. I personally have grown weary of pages with little to no information and half blurred pictures of people in coffee shops. And don't get me started on the scroll bar tricks....
