Well I really like how the top comment in a thread doesn't stay that way. On Reddit there's a problem where getting to a thread first puts it front and center. That isn't happening here except in very low-participation threads. I still have my old Reddit habits from using this site, like checking my profile page to respond to reply alerts, and I've been delighted to see that new posts in an old thread rise to the top. So the new sorting algorithm seems to help. Whoever's idea that was, they have my kudos.
