That's what Slashdot has, and why it has persisted throughout the years. I've always loved that I can come to Slashdot to learn what truly educated and intelligent people have to say on the matters of the day. A story on Lockheed Martin? One of the team members will probably post the scoop on what's really happening. That is useful knowledge. It is valuable to me. Part of why it developed was the infrastructure of the site and how it allowed the best discussion to float to the top. Part of it was an absence of anything really like it back in the day. Part of it was happenstance.
But now that all of us long-time Slashdot readers know what the shape of the best form of Slashdot felt like, I believe it's possible to re-create that elsewhere, especially if the PHBs at Dice absolutely insist on killing this precious object. Furthermore, there are many of us who have great ideas on how to recast Slashdot with new features that would enhance the community, not detract from it.
Call out a channel for all of us to discuss what that is, and we'll hop on and iron out the requirements. An open source community redesigning itself would be an excellent reaffirmation of the principle of open source.
