I don't know, doesn't seem that nuts to me. I'm a GM and I reckon if I'm going to run games for years for people for free, I had better like them and know a little bit about them.

I wouldn't say it was a fun task, but I wouldn't go so far as arduous. I kinda like reading everyone's answers and, if I'm being quite frank, I'm not above admitting that so many people trying to get into a game I run is a nice feeling.
