Happy to see some cross pollination between Slashdot (my go-to from 2008-2013) and HN (my go-to from 2013 till now). Also happy to see that Slashdot comments have not really devolved and remain readable and useful.
I've noticed an upward trend in the quality of comments on Slashdot since the Great Reddit Moderator's Rebellion of '23. It's worth giving Slashdot a quick check every once in a while.
