I only have a 5 digit Slashdot ID, but I remember the early days. I really, really liked /. back in the day. I don't remember what happened to drive me away but going back now the content seems to be very similar to what's on the HN front page now. However, there's something about the look and feel that is off-putting to me. Maybe its the fonts or the stuck in the 00's design.
You're right, it was a pretty good way to do moderation. As in everything with software, what old is new, right?
