To be honest, I have gone back and forth on this since the first post, but actually my problem, for what that's worth, is not a 'like' or 'dislike' which are factual responses and need no real commentary, but the use of emoji to connote emotive reaction.Well if you want to be at that level, no emoji really conveys the underlying thoughts , but that is not a reason to not use them.
For example when a post is liked what does that really mean? The entirety of the post is like, one paragraph, sentence? Same for disagree. And why shoul disagree or angry require further discourse while like doesn’t?
Or we can accept the emoji system is imperfect and it’s another facet of social media to be used, not used, embraced or ignored.
I agree entirely that we don't have much option but accept they are part of the landscape, however imperfect they are, but my objection to their use here remains as I posted previously, simply because in the context of the OP's question, that's my opinion of their use, and I though it more helpful to express it in a post than click a button.
By the way, I don't personally understand most emojis - I can't get any meaning from most of the faces - so by default they serve little useful purpose for me. A thumbs Up/Thumbs Down or tick/cross would make more sense.
