For Peroni, look up altruism in the dictionary. Valid point. I was exceptionally grumpy this morning. My thought process was why would people go to the bother of doing this if there wasn't anything else in it for them? I agree that a lot of people will use it purely in order to help people but to help drive traffic there must surely be a system that will keep bringing people back. HN & Reddit have karma for comments & submissions and whilst karma is worthless, people feel compelled to generate as much karma as possible. I wonder if a similar system could be implemented with this site?
