Re: Lee D
Unfortunately they do have better things to do but would rather waste time on emoji. I read an article about a linguist that was getting fed up with the emoji focus especially at the expense of research into ancient languages.
I can't find the original, but here is a link to a similar but less serious article.
Note: I've got nothing against a basic set of emoji to convey common concepts like happiness, sadness, humor, etc. I just think the situation has gotten completely ridiculous.
