The site is labled "visual stastistics" but where are the visuals? Give me at least one pie chart, i know you love them. Clicking on a fact gives you nothing more then you already knew, so whats the point? Disgustingly over compressed jpegs. Somewhat awkward navigation.
Feels very on-brand though.
Interesting... I used to work with Microsoft and I was toying with doing the side scrolling for one of their other sites, but we decided against it in the end because it was a bit jarring. Wonder what other people think...
Other than that, it's a nice simple design. Wish there was a bit more behind the stats when they came up, but the UI is nice and snappy and sits well with the Windows 8 design :)
