Jared Sinclair, on his personal blog, on the new Dark Sky:
The raw idea for the redesign is good; the three-panel view with a side panel for the globe is an interesting riff on two established navigation patterns. But the execution is sloppy. It lacks clarity. It fails to shape the data into visually coherent elements. Titles are indistinguishable from content.
He has some good reasons for his critique.
