I agree that "7 degrees of reddit" or whatever is bending the rules too much.
Something like a hard ban on politics might lose things that are of interest. For example, what role are technical tools playing in the arabic revolutions right now? Obviously Wikileaks, reddit, youtube, twitter and facebook are playing major roles. And what role are hackers playing? Assange, Anonymous, and the Egyptian Google guy are all using technical skills to create worldwide revolution. That's pretty exciting, using technology to make political change. But should discussing it be banned? Is it necessary to ban that to get rid of the various latest cop shooting incidents reposted from reddit where technology is at most a minor role.
BTW, tagging a story as political doesn't cause it to disappear; it just ranks lower, but would probably still be on the frontpage if it had a lot of points.
(b) Because one minute there was a 200+ story at the top of the page less than a day old, and the next minute there was no such story at the top of the new page, and yet the story hadn't been flagged.
How is this not politics.
