As a mod I can tell you, I try to promote everyone who I see as espousing the general attitude of the Nexus. However, I (and I assume the other mods as well, but won't presume to speak for them) am human and have a life outside of the Nexus. As such, there will be time periods where I don't promote anyone, although no doubt there are many who deserve promotion. This is nothing more than the effect of my own exhaustion/schedule but it has a real-world effect that has direct bearing on new members. As such, if there is a mechanism we can put into action that allows for us to, at a glance, see that there are members who warrant promotion (and don't need us to have interactions with them or read through their prior posts in order to establish this), I think it's worth a shot.
