Chrome. There is an image at the top of the page, but the 'App' section has a light blue background.

In fact, the following sections (support, operations, social, etc.) don't render at all for me - just a background with no text. Is the page not broken for anyone else?

edit: Interestingly, the page doesn't render for me above a certain width of around 1000px. Was this intentional? It's pretty bad design either way.
