I think emojis can let your friends use less than a second to know what your feelings is and the Expression is much clearer than words ! But in working place, better use words then!

Omg, my mom doesn't understand the meaning of emojis at all!! I always tried to explain that this picture means this, that image means that, but for her it is just meaningless pieces of art without any communicative aim. But she never uses any messengers, she uses the simplest phone and prefers quite an ascetic way of life. However I believe we can find lots of people who just ignore emojis.

I like to use them to express humour sometimes as text can be very open to misinterpretation. I don't usually use more than a couple though as I think they can detract from what you are trying to say.

Emoji can also be easily misunderstood as well . They are confusing a times and one have to think well in order to understand the emoji .

I love using emojis. They add a bit of expression to the virtual conversation and I believe never did anyone any harm.
However, it my not be okay to answer the entire conversation with an emoji. ( I would like to know what was funny or made you angry about my communication)
Emojis may not be appropriate in official communication. However, it always depend on the relationship you have with a person, it is a virtual expression of your feeling and we do not reveal everything to everyone.
