It could cut down on clutter and also potentially increase the number of visible participants in a given conversations therefore creating a greater sense of an active community within a Guild since so many responses to a given message come down to a Yes/No answer. Or there could be messages to which one certainly wants to show support but not necessarily know what or how to say. Or someone might not enjoy typing on the app- they could still express their stance in a quick and easy way.
