Here it looks like six people liked this item,
when in fact it could be instead six hates.
Same for the heart symbol seen here on meta.
Maybe a Category:Comedy and tragedy mask icon - Wikimedia Commons would be better?
You know, more “emotion-inclusive”.
Also one cannot get emotion count details, without expressing an emotion oneself. And then there is a limited time to withdraw your emotion before it becomes permanent.
Why would you like something you hate? You just wouldn’t react with the post. In my opinion anyway.
To convey emotions better there is the reactions plugin which is enabled on meta.
To add on to what Moin said below. If its just a 
(no reactions) you have to press on the number of likes to show who has liked the post.
I don’t have a problem doing that:
이 Contribute > Feature 요청은 @jidanni 님, 좀처럼 이해가 되지 않습니다. 기존 UI에서 이미 다루고 있지 않은 것을 제안하시는 건가요?
This should do what you want
Though not sure but think the reactions plugin also let’s talk ne now change default like icon
I’m pretty sure it does, IIRC it allows any FA icon to be used.[1]
I would check, but our forum is out atm ↩︎
I found the problem.
In the image that I posted, when I hover my mouse above the “6”, no mouseover is produced.
The relevant element is
<div class="only-like discourse-reactions-counter"
id="discourse-reactions-counter-1026062-right"
data-click-outside="true">
<div class="discourse-reactions-state-panel max-length-1"
style=""></div><span class=
"reactions-counter">1</span></div>
it should have a mouseover saying “click to see details (about those 6)”.
