Simulated Reality: which of you are the NPC's?

So everybody is having fun creating their little Metaplace virtual worlds. We set them up and then populate them with non-player characters (NPC's), allowing real players to interact with the NPC's. It's a lot of fun.

I recently found this wikipedia entry:
http://en.wikipedia.org/wiki/Simulated_reality

Did you catch section 5.1? I know I'm not an NPC. Are you?
