I think I’d use that as a very loose rough guide with a pinch of salt. I had no idea that this was what the intended use for these buttons was, I always likened the like button to some pointless added clutter like what you might find on some social networking site, I jab it from time to time, didn’t realise it was meant for anything useful though.
I think you should mention how you expect people to use some of these features if they are not how you would expect them to be used. Would help if Discourse actually worked properly to start with, I haven’t bothered looking into some of the quirks of the forum but Jeff is busy reinventing the wheel for some reason and there’s enough people doing pointless things these days so I just ignore most of the forum “features”. Why do topics have some sort of quad state view? What is a badge meant to be for? Why do we have to have infinite scroll? Why can’t it count properly?
