I think most of us would be quite happy to move on to other things, if you'd just let us. Which makes it all quite simple: Want us to stop talking about Jack? Stop reading about him.
With all due respect, this is absolute rubbish.
First of all, you people have the power of agenda setting [http://en.wikipedia.org/wiki/Agenda-setting_theory] on your side. It may not be pretty, but go ahead and take some license in what seems newsworthy. Not all papers cover the same tripe. The New York Times ignores the stuff that People covers. Let some other "news" sites cover Jack Thompson.
Second of all, even those of us who seem to be reading about him with you here aren't necessarily doing so. Yes, you will see me registering on your pageviews/requests as I pull links to all your (and Kotaku's, and Joystiq's, and Game Politics's, etc.) articles. Yes, I skim everything I have time to skim, assessing what is actually relevant before I read. And no, I am not interested in reading the stuff about Jack Thompson — except the posts about whether we can stop talking about him, hoping that they will end with a pledge to stop writing about him. You let me down on this one.
Seriously, he has moved from mildly threatening through loveably zany and into irrelevant. Don't lay this on us. Please write about things that matter to the development of gaming as an industry, a medium, and a culture, and quit pandering to an audience that can get amusingly sensationalistic junkfood elsewhere.
