Personally, I'd rather have more players that know the tricks of the game.
When I play a boardgame, I get no enjoyment from exploiting the new guy's lack of knowledge. I think of the game Diplomacy, which I love. Playing with new people is fun because of their excitement, but lame because I always win, and I win, not because I'm smarter, but because I've played it so much I know the best moves, and I can calculate supports, moves, support cuts, convoys, etc in my head. New people who are less experienced and don't know the rules can't do so, and they lose.
But when I play with a group of experienced players, it's more fun. We don't have to re-explain every rule, we don't have disputes about fairness and unknown rules, and it's more up-in-the-air about who will win.
BM, obviously, has no winner, so it's a bit different, but the point still stands. I would rather play with people who know what they're doing.
And when that new player doesn't send food even after I've tried explaining it, and finally I get the judge to fine/ban him, and he complains about "Oh, there was this one thing I didn't understand," it simultaneously makes me feel like a jerk and takes away his fun.
This way, I've written a guide so that the learning curve is reduced. Higher-level play involving food politics is much more accessible to new players. I'd rather appoint a new player as lord and have him immediately negotiating competitively than boringly set up an automatic transfer. More chances for RP.
