0E800 I still don't understand how you can agree with something and not like it also.
It's not just about liking, I think it's more about strong indications (reactions). Simple like is for just liking as in "I liked the explained reply you gave or the way you explained a case". Agreeing is also liking but, more than just a simple like - "I liked what others have to say but I agree with your statement as it makes the most sense".
@jordanjay29 @0E800 yes it's more of like reactions only but in a different way. Reactions say that a like is a like, ? for more than just a like, even exited/wow then a ?, doesn't like then a ?, touched your heart or just awesome kind of feeling then <3. These are a really good way of telling how you liked a post or a reply by emojis but also are best suited for social forums (light content or content sharing forums).
The type of reactions which are in image above are also the same but more dedicated for an informative forum. Forums in which there are strict rules and more emphasis is given on a good reply and information is being shared then this kind of agree, information and like are a good way of telling which users are providing extremely good information.
To sum it all, "reactions - like - the image above" are all iterations of the same thing but still different for different type of forums as I think about it. Although this can also be made into reactions extension with options to choose between reactions or "this style" and the admins can choose depending on the type of forum they are running.
Even I wasn't sure whether it was different or same from reactions but from your replies I actually have a better understanding of these now. ?
