I read Slashdot for many years however Hacker News has replaced it for me now. The quality of discussion has become very poor over there plus the stories are often a few days old before they hit the frontpage.
I think the summaries are the thing that make me stay on /., especially as HN has strict no-editorializing title policy. I've many times missed an interesting story on HN, then read it from /. and came back to HN for comments.
