Of course, when someone tells you his mother died and you smile like an idiot, it surely will not create a positive effect.
The way I understood OP, it seemed as if - in a normal setting - smiling would be frowned upon when talking to people in general in some places... which I find hard to believe.
I'd like to know the culture where smiling is seen differently. It is the global symbol of happiness and tells everybody on earth "i'm a friend" or at least "i'm friendly".
What did you miss in org-mode that your tool is going to have?
I can't think of anything, so I don't really know what benefits your tool provides compared to org-mode.
