HN is not a good place for conversation. (I wrote about this once and it was sorta well-received and then, case in point, everyone forgot about it the next day.)
HN is primarily a news feed. There is some discussion, but it's topical and very short-lived.
I only mention this because the site seems a lot better once you give up on the notion of it being conversational.
Hmmm, yeah. I see your point. If two people really just want to shoot the breeze (I don't mean that flippantly), or get to know each other better, or talk about off topic things, then an e-mail is a much better way to do that.
I'm specifically thinking about topical conversations or discussions, where someone asks a question in a thread, or brings up a point and someone else finds it somehow and answers the question, which can lead to a series of enlightening posts/responses.
I like the HN comments because they have people who disagree, as long as the disagreement is civil, informative, and doesn't seem to have too much ego tied up in it. I like the reality check the comments offer.
I wish it was more conversational. There are lots of experts on here from a variety of disciplines, and a meaningful back and forth can be great on here.
But, it's not a good fit for the current format. Perhaps if when a thread got too deep, it could collapse and require a reader to actively expand it. That would help support the threads that start to push too far to the right.
But, it's probably better dealt with in a full redesign.
There really needs to be an entirely new kind of discussion forum, something that merges the various strengths of phpBB, IRC, newsgroups, and reddit. I have some ideas on that, but sadly not the time to code it. I hope someone beats me to it.
I like conversational places. I guess a lot of this has to do with what type of place the creator wants to create and how they want to try to mold it into that.
My ideal place would clearly define types of behavior that were to be discouraged. For instance, I like to err on the side of suppressing vitriol too much, rather than letting it run too much. I like environments where everyone feels like they can try to contribute, or participate, without wondering if it'll come back at them. I have pretty strong feelings about how far that should go, though, and it's usually further than a lot of folks would, or at least, further than a lot of vocal folks would go.
But I guess that's just it. I think generic karma/votes tend to promote a more general idea of what's popular, or fun, but don't necessarily promote a specific well-defined ideal.
I read HN as much for news links as for the ensuing intelligent discussion and pointers. Should you take them away, to me, the appeal of HN drops significantly.
