The New Yorker website is definitely among those well-designed news websites. The Gestalt Principle is applied throughout the site.

• proximity and alignment: achieved through dividing content into two/three columns and align them neatly.
• similarity: through placing images in square shapes of the same size within each section; same typeface among each section; unified format in each “story box”, following the rule of headline-author-brief summary-section name.
• visual hierarchy: achieved through smaller intro texts following bigger headlines; also achieved through use of difference sizes of images.
