Spelling in matters that, and that

Hello, I think, by now about 95% of all users here need a refresher in the spelling material 1. Class primary school: “That” is not the same as “that”. The word “that” used to be “that” and has a vaguely different meaning than “that”. I have been reading almost exclusively stuff lately, in which practically no “ß” or two small ss occurs anymore or the two small s are used wrongly. At some point, it is hugely annoying if you just have to read: “.. .that’s how it is, I said yes…” “that’s awesome…” etc. If virtually every adult person doesn’t check the new spelling or has a fault in his finger and can’t press a letter twice in a row, how about just unpacking the good old “ß” again? Always better and more understandable than this invasion of the incomprehensible letters.
