Honestly, at this point the lag is kind of the draw with Slashdot. Once a story has shown up elsewhere, you can go there 6 hours later or the next day and everyone has had time to mull over the story.

Scroll down to the middle of the page past the typical trash comments and you can find some useful info, often from old hands who have had a some first hand knowledge of the subject.

Of course that is also the downside. Every troll, malcontent, joker and astroturfer has had a good 6 hours to harden their position.
