Interestingly, this post appears to have been flagged or relegated in some way. It has 141 points in one hour at 10th place, while the Steam Family Sharing post has 150 points in first place and is two hours old.

Certainly some of the discussion on other threads should be filtered. But the moderation on stories themselves appears to be heavy-handed right now. Many significant new stories aren't making it to the home page (see above).

The official guidelines for flagging are: "If you think something is spam or offtopic, flag it by going to its page and clicking on the "flag" link"
