I think the old version of emojis(like :) :| :( :D :P ………)are more then enough for adding expressions to your text.
Also I don't really like emojis because on most mobile device the capacity of symbols is limited and therefor emojis often replace useful (math) symbols(like ¹ ² ³ ⁴ ⁵ ⁶ ⁷ ⁸ ⁹ ⁰ ⁽ ⁾ ⁼ ⁺ ⁻ ₁ ₂ ₃ ₄ ₅ ₆ ₇ ₈ ₉ ₀ ₍ ₎ ₌ ₊ ₋ ∇) I cannot write anymore.
And in general I think most of them are completely useless. Some people tend to place the emoji resembling a word behind the word(like "…cherrycherry emoji…").
Also I think as useful as they may be they can also lead to some confusion at the other end because most emoji look the same on first sight.
Also a problem is if the sender uses a wrong emoji or something.
So I would say they are no advantage.
Haha... a dedicated old fashioned emoji lover! I love it! In many ways I'm the same... the old ones were enough, after all, how much fine nuance do we really need... and how many do we have before there is a fundamental lack of how the are perceived between author and reader.
