Is there any way of knowing which posts have been applauded though?
As far I am aware, no. It is just a count based on an individual's overall popularity irrespective of which of the individual's post were applauded. It doesn't have a function to say which post was applauded but I'm not an admin on this site and don't know what features (if any) the karma function provides behind the scenes. I can't imagine anyone using smites here......we are all friendly bunch :)
