Thanks for the answers. So it's actually good to have less survivors.
I guess you could say that. I mean you need 12 people to get either the warehouse or the farm which are the best places in the game. After it is built though it certainly doesn't hurt if a few useless people (like Ed who is good at reality tv trivia or that one girl who is good at sexting/gossiping) get overconfident while fighting zombie hordes if you know what I mean.
I hate to break it to you but if you don't have any particular skills to contribute to my community, you are on your own buddy.
