Seems to me that writing using Emojis requires significantly more effort than writing it using just words. Besides the comical factor, I just do not see the advantage here. Correct me if I am wrong, but there would be certain phrases that you could not say in Emoji, it would struggle with slang and other made up words. I probably would not back this, but I cannot deny this is not cool and unique, I will be keeping my eyes on this to see if it goes anywhere.
