Some feel weird to me and recently I noticed that it also depends on the culture how people interpret them. Since then I rarely use them. It saves also time, although...an emoji, the right one, can also add something extra to text for example how the words are meant (angry, joking,and so on).
As I saw the first line of your text, all those emojis it made me think of one of the first CCC contests I joined hosted by @marblely... we had to write a story by using mainly emojis. It took me the entire Saturday to search them one by one.
