Have you noticed that exclamation points seem to be becoming 'trendy' in modern communication? They are everywhere! (see?) An exclamation point is used to communicate a person is exceedingly [insert feeling here]. It's like saying AF without using language deemed vulgar by society.
As a result, exclamation points have been somewhat less effective for some people, in my estimation. I sometimes think to myself, "Was there really a need to use an exclamation point there? What did you achieve? Calm down. You are annoying yourself. If you keep using them so 'willy-nilly' the person on the other end will never take you seriously when you really do need to exclaim something." God forbid.
There are also days when I think, "I'm going all out today so I'm passing it on by flowering the world with exclamation points!" That sometimes leads me to feel that if I am not feeling exclamatory one day in the future, I might let people down by my lack of exclamation points. Consider this my exclamation pointless pre-apology. Don't take it personally, its me, not you.
Exclamation points have also created more work for us because of IEP (Imposter Exclamation Points). I just made that up. The other person might use an exclamation point to merely 'appear' a certain way - an IEP. The receiver may have to re-read the text or email or message several times to analyze what was meant by that little line with a dot at the end. This is a good time to not assume. Or assume the best and not the worst. It can easily deteriorate from there.
