True, and my other post wasn't as clear as I meant it to be. I intended a helpful "Take charge of your gaming experience man! Be pro-active!" and it came out more "Hey! Maybe it's your fault! Huh huh? Yeah, you jerk!"
I've been on both sides of the "This gaming is going nowhere," and I'll say it's much harder to get players to step up and be driving forces in the story if they don't want to be, or are unaccustomed to being strong driving forces, than it is to get the GM moving.
