Timothy et al, please just stop and look at what you're doing. The beta is awful. The beta is awful because it seriously fucks up the one feature that has made Slashdot a site worth using since its inception: the user contributions.
The stories themselves are rarely why I bother to check Slashdot, I've always been more interested in the discussion. The discussion on Slashdot has been more interesting than the stories for several reasons. One major reason is the discussions would almost always add information about a story that wasn't linked to by the story itself or the editors. A Slashdot post would bring up a topic and then allow a bunch of nerds with an interest in that subject to chime in and share what they knew. Many times the people being written about in the Slashdot stories were Slashdot users themselves and could give first hand information.
Besides the contributions themselves the moderation system is actually pretty damned good. Positive discussion more often than not gets highly promoted. Because of the way mod points work there's little incentive to do anything but promote interesting commentary or demote outright trolling. Because of this system it's pretty easy to find worthwhile discussion no matter the topic.
It's because of these things that Slashdot's value comes almost entirely from its user contributions rather than news aggregation. In 1997 news aggregation like Slashdot was new and interesting. Today every site does it. What every site does not have is an intelligent and interested user base that will add value to the stories themselves.
The user comments section of almost every large website is a cesspool. Not only do they not have meaningful moderation but there's no community interested in promoting discussion. The design of the sites themselves also discourage long form commentary and encourage useless drive-by commentary.
In short remember that Slashdot users are not an audience, they are a community of contributors. Without the users there is no Slashdot.
