This is why I love love love reaction icons. First used these a lot in Slack but now I want them on everything. People can feel like they've acknowledged something (and even provided their sentiment to it if they want) without having to feel like they need to provide an opinion.

100% agreed. Reaction emojis are a huge innovation in online participation, and they serve a lot of the same functions as non-speech behaviors do in group conversation.

I'm in one large Slack where people have contributed an extensive library of custom reaction emojis and it's great. The place has a strong culture and a lot of great in jokes all expressed in relatively few pixels of screen real estate and relatively few seconds of comprehension. It also diverts a lot of energy from what would otherwise be low-value comments.
