From Game Newser: "By now, you've probably have known about something that N4G has used called the "Source Filter". It's intended purpose is filter out "flame bait" stories by "unknown" blogs in favor of trusted sources.
Notice, though, that I said "intended". I decided to do a comparison today, and found something peculiar. On the 360 section of the site, there are almost no stories from sites that are caught under the filter. On the PS3 side, there are more than enough to raise suspicion. Could the Source Filter be just giving fanboys another way to control the site?"
