I see emojis as text’s substitute for body language. Body language is supposed to supplement the spoken word. Emojis should supplement the paragraph.

Trying to communicate with more emojis than text is akin to trying to communicate with more body language than spoken word.

Ever try to say something but forget the word, and you try to convey the meaning with body lamguage instead? Overuse of emojis implies a similar lapse of thought.
