Reducing Pesky Fan Noise?

Thanks to FiringSquad for their editorial about how gamers and developers interact in public forums, inspired by Alex 'Marweas' Rodberg's public outburst in the HomeWorld 2 forums, which in turn inspired a Penny Arcade strip about the trials and tribulations of being a 'community manager'. The FiringSquad article suggests that "...there's an increasing divide between the people who make the games and the people who play them. And guess whose fault it is? It's yours, not theirs", and goes on to venture that "Online interaction is so impersonal, so fraught with assurances of anonymity, and so littered with the maladjusted and juvenile, that there are no social repercussions for acting like a jackass." What's to be done?
