/. missed the Digg and then the Reddit train.
Doesn't surprise me, still has teh same shitty interface more or less from the late 90s. Won't even tell me if someone replied to one of my comments without me looking manually. Doesn't display correctly on tablet/phone, can't select post display setting on said devices.
This so called tech site sucks in a lot of ways.
Not sure how you expect to get notified of replies as AC... try logging in, and you'll have the option of various forms of notifications when someone replies to your comments. And a phone/tablet site was launched a few months ago: http://m.slashdot.org/
