I really have a hard time with emojis outside of communications. Either they are saying something that was already said by the word or words before, and in that case they are useless, or they replace a word and make text harder to read. I also really don't like the concept of making objects into emojis, as we already have words to describre that, and emojis reflect a very limited world. For example, if you look at the food emojis, this is basically "I live in San Francisco and all of the food I get is from restaurants". I think I've heard it described one day as "the world of people that live in airports", and that fits well.
