Love it! It's great to see web design finally start to scale to large and wide screens. I hope this is the start of a movement.

Have you seen pressreader.com's layout? eg. https://thewashingtonpost.pressreader.com/the-washington-pos...

They have some really nice ideas, implemented well. See for example how the articles click to expand. And the horizontal scrolling there works so well with the columns!
