> HN certainly isn't a utopia, and a lot of the problems mentioned are just inherent to online forums.
The old style of forums didn't have the same kind of compulsive pressure, since you could always respond the next day/week/month and the topic would bump back up to the top of the post. If you don't respond on HN or Reddit quick enough, no one is going to see your comment. I frequent some sites that has the older system, and I'll find myself occasionally saying "This isn't that important; wait a few days and see if you feel like responding." But that's not really much of an option here - how many people are going to read your comment if you make it several days later?
And it wouldn't be hard to devise a system that actively discourages compulsive posting behavior. If you, say, had a web forum where everyone could only post once a week, you'd have much less of that urgency (and you'd get a discussion with more users, not just the fraction that habitually post everywhere).
Yes, HN and Reddit are very-high-traffic forums, so it is mostly read-once--write-once--do-not-come-back. Not only the comment go by hundreds on each thread, but the threads themselves have a life expectancy of 24 hours only, 48 hours max, before they are buried and reject to the infamous page 2 where no one goes. So there's generally no point in coming back.
The fact that the 'shape' of the threads changes all the time does not help either (the way the messages are ordered, depending on the upvotes, the freshness, and whichever mysterious other criteria may be involved).
Conversations at a depth higher than 5 or 6 levels is also difficult to follow, so I think not many people read them, let alone take part in them (on Reddit, such deep threads even suffer a penalty twice, and the second one, which requires opening a new tab or window if you don't want to have to reload the whole page once you come back, is probably fatal to almost all of the readers).
(I won't tell how much I miss Usenet and newsreaders once more, I promise :-D )
Do you think it would help to have a comment reply notification built into HN? Most of the time if I decide not to add a follow-up comment it's because the user I'm replying to has no way of being notified that I did. Or do you think it would just exacerbate the urgency issues?
That might be somewhat useful, but the thing is after a few hours your conversation with the other person is going to be no better than a private message (since no one else is going to see the topic). Web forums bump the topic back to the top, but that kind of defeats the purpose of the "news" angle. It might be interesting separating the two - have the submissions act like they do know, but have the comments for the submissions be in individual threads in a separate discussion forum.
>It's nearly impossible to keep up with anything but recent conversations
It's been implied that this is an intentional means of keeping engagement low, as the quality of comments tends to diminish over time, while the likelihood of flamebait and spam increases as comment distance diverges from the root. This is also apparently the reason there are no notifications for new comments. I don't know if it's true or one of those features the community is reading too much meaning into, which only exists as it does because pg wasn't interested in expanding on it.
In any case, I really hope they consider adding more ways to sort the threads - sorting by time rather than karma would be very helpful. They could even keep the karma sort the default so no one else has to complain about the layout changing.
