Having been on sites that allow negative feedback and having used Discourse at our site https://swi-prolog.discourse.group/ which currently only allows like votes (think positive reaction) I plan to only allow positive reactions in the default set.
While I am aware that there is the Discourse voting plugin (think binary positive and negative reaction only) I think it would be beneficial for an OP to be able to select the reactions allowed for their topic. I know that is not a simple change so would not expect it anytime soon, but something to consider.
Most definitely.
I have been patiently waiting for this plugin for many many months and am more than happy to see it moving along in the pipeline.
Nice job everyone!!!
