I think I’ve settled on the latter. Disagreement is maybe best communicated by the absence of an upvote? And downvotes work best when they signal something that is just off base, and while not reportable, is not appreciated at a broad cultural level.
Enter: the wheel of upvote options and the multidimensional spectrum of downvote options. Don’t worry, I’ll ask Google to analyse my life history and feed it into the emote-i-vote.
Come to think of it, I like the attach emoticon thing in GitHub (and lots of other social media? But I’ve liked it in GitHub) to get a relatively convenient and concise expression of “I like your message in this particular(ish) way”
Yea emoji reactions are fun. Calckey has them and it works well.
