I get how this could swing both ways – good and bad, but I think having a reaction system on the forum would be cool. For the silent lurker, I think this is a good way to participate without commiting to a full post. I do not fall into that camp (ofc), but for us yappers I think it also allows us show love for things that may walk the line of needing a reply. IC posts specifically, IMO, would benefit from this.
Pilgrim AND pof Zahra, if you see this, do consider it my laugh reaction to your memes <3
