While I appreciate the desire for timely news, there are also up sides to the delay.
One big up side is that the story has somewhat settled down and there's more facts going around than speculation and knee-jerk reactions.
True, but at the the same time, doing this also removes a lot of input from people who aren't necessarily going to be interested in the topic still. Which may not be a bad thing, but at the same time it removes a lot of the momentum from the conversation, and potentially results in a lot of "dead" topics.
If you're going to try for something like this, doing it sort of like Ars tries to do with their "feature stories" seems like the way to go. Let an expert/writer try to offer their own take initially, perhaps come at it with a different angle, and then let a new conversation spring from that. Of course then the problem is that you have to have people who can generate unique content of some length, rather than just reposting articles with maybe a short blurb.
And let me be clear: I'm not suggesting that Slashdot has to "Go Giz" on us, rushing to get stories up so quickly that half the time it looks like a second grader wrote it, but I do think there's benefit in putting up submissions for most stories earlier. SlashCode is pretty good for allowing long, detailed discussions on topics, and most of us have plenty of practice doing so. The community here used to be epic, and it's still pretty good, but I'm convinced that a lot of quality commenters don't show up here any longer mostly because they've gotten used to offering their comments/opinions on other sites. When something interesting happens, you naturally want to discuss it, and it's just frustrating knowing that you might have to wait a significant amount of time for Slashdot to put up an article on it.
