I think we all liked Shog9's graphs for the close queue..
I also think that if we would have live graphs like the one above or something that would show in the same graph how many questions are ending up in the queue per day and how many are actually being closed it will be more interesting and will motivate people to actually beat it.
One other example is Reddit. When somebody learned that despite having 70+ million viewers, Reddit is actually not profitable and in the RED... everybody start buying more gold to random people just to help. Reddit responded with a nice daily reddit gold goal thermometer, which I believe since that day, they are not on RED just by showing it to the readers :)
So my wish is to have some cool graphs that Shog9 did, but live and interactive (not necessarily the one I posted above, that was just an example).
