CSS4 is a Bad Idea
5.2.2020
Louis Lazaris, reacting to the idea of CSS4:
The reason “CSS3” worked is because it was real. It was the successor to “CSS2.1”. Everything after CSS2.1 was considered to be under the umbrella of “CSS3”.

Edgium
22.1.2020
January 15th, 2020 was the day Microsoft Edge went Chromium. A drop in browser engine diversity. There is a strong argument to be made that's not good for an ecosystem. Looked at another way, perhaps not so bad:
