I've had a job where I needed to know weather conditions in multiple cities, and weather.gov is like a flat grey, white and powder blue excel sheet. Meanwhile weather.com is covered in all kinds of animations, and videos, and has much more modern and busy looking visual design and a hundred ads. It's so slow, and if weather.gov was down I'd be so mad that I had to glance at weather.com.
Love you weather dot gov, your minimalist design and minimal system requirements are beautiful to me.
