I am all for repping RPG - it is just that I don't read a lot of it unless I am involved in it. I have been known to rep particularly cunning / skilfully crafted Quiz questions or answers. They may also be manifestations of great knowledge and love of the Prof's work.
If I have made a change in my repping, it has been to try to cast my net wider. I don't always succeed but I regard it as a failure if I get the command to spread it around to often... but then it is hard not too when some folks post so well so consistently.......or just make me laugh so much...
