Outside the several mailing lists we have, there's nothing resembling a central repository of security research and industry gossip. It's possible that it all could be done better with a custom web forum, a VIP room on Chatroulette, or a well-designed UUCP dead-drop - but so far, despite many attempts, nobody really succeeded with that.
Plus, F-D is awful mostly because it's a fairly accurate mirror of the security community itself (and certainly many of the web forums I have seen). More often than not, this is what makes the headlines - not a novel sandbox escape exploit that bypasses kSLR.
They perform slightly different functions and rely on a higher level of trust than an open mailing list can deliver but the security community is not uniformly awful.
