We use Slack at Kinsta and one of the things I enjoy about Slack is the use of Emojis as reactions. Not everything posted in Slack needs a typed response, at least not from everyone in the company. Emoji reactions allow you to respond without creating a notification that the poster then needs to review. Instead they can glance at reactions to their posts in Mentions & reactions view.
There are a lot of emojis in Slack and you can add as many as you want. These are great and allow you to react with a wide variety of reactions that communicate nuance and personality. However there are times where nuance and personality are not needed. Instead I need to give a strong affirmative reaction and that is where the 👍emoji is my workhorse.
The 👍transcends language and emotion. It shows approval and support for whatever was posted. If someone reacts with the 👍there is no doubt as to what they mean. There are other emojis for other occasions that do the same and maybe someday I will talk about those too.
