The thing I sometimes deal with is not knowing what the abbreviations stand for. Also emoticons are used a lot. I am guilty of that.
At work they asked us to stop using cursive writing because younger people are not learning it and cannot read it.
What's next? LOL (sorry I like writing that one.) Oh yes and 😇
We had the same issue in school concerning cursive. The parents couldn't read it :0 They are a handy form of short hand but the real problem that I'm getting at, is that many people have never learned the long form of writing. So they are stuck with this limiting form of communication.
