I think the main difference between HN and Reddit is not the quality of the links (in the stories they share they have similar links and most of them come to HN later than Reddit) but the ensuing discussion. In fact most of the time I don't even click on the link on HN (for topics I already know about) but go directly to the discussion. I also tend to save the HN discussion page to my Delicious, not just the link, because of the value of the discussion.
That being said, I don't think the discussion on Reddit is worthless at all. Yes, there's quite a bit of joking, which is good to read at 4pm when you are stuck at a bug. But this particular topic is an excellent example of the value of the Reddit discussion: reading through the jokes, etc. provides interesting thoughts about implementing the TWSS bot.
So, the two discussions are complementary. For particular stories, I head over to proggit and see what the Redditers have commented.
