I agree. And Twitter, where editing isn't possible and everything is forgiven, is not improving the situation.
Many years ago--back around 1997 or 1998--some Silicon Investor posters realized their language skills were inadequate, and asked for a spelling and grammar board. They really wanted to do better.
That board was created. And at first it went well. Unfortunately, people lost interest pretty quickly, I think because it was like work. And within a few years, understanding the rules of their native language became unimportant to them, and to a great many other people.
