Is the concept of negative numbers really a problem for people to grasp? If yes, then we should teach that instead of using Kelvin to make it easier for them to know which number is bigger.

Today it's just reading consumer social media. For HN readers, that means when you're at work, don't assume the people sitting around you are on the same wavelength as you in any objective sense.
