One of the biggest advantages of Antionline is that there are so many people contributing. As a security administrator I can visit Antionline for updates and information on almost any security-related subject rather than visiting each vendor site and each security site (like SecurityFocus or PacketStorm) myself.
To take that one-stop-shopping to the next level you should set up some XML and implement an RSS feed for the site.
If the site had an RSS feed of the main page or maybe just specific forums they would receive an automated notification when there were new posts and that would drive traffic to the site rather than just waiting for people to visit the site and stumble upon the new posts.
Of course, maybe the volume of posts would overwhelm someone using an RSS feed reading program. Just a thought.
