Absolutely, and it isn’t to say I never use emoji/emoticons but I don’t on social media that much. You can convey emotion and vibe with a bit of nuanced typing. This is likely lost on some folks but others seem to be tuned to it, almost like body language. Grammarly actually has a tone mapper built in to tell you what sort of tone you are sending out.
Emoji might be the right choice there. Sometimes I’ll just send back 🤷 or a gif in text messages or quicker formats but for something like Lemmy or Mastodon, I think a more effortful reply is desired since the point of those services is the conversation.
