> Isn't the reason you use that service (waste less time here) specifically to avoid getting drawn into the discussions? Serious question! :-)
No, not really. There is usually ~1 article each day where I get interested in reading the discussion. When that happens, it is often disappointing to find the discussion high-jacked by a top-voted comment that goes in a direction that doesn't interest me. I'm sure there are interesting comments further down the page, but on this site it's hard to find them. I think Slashdot handles this a little better by letting you set a point threshold.
In the even fewer cases when I want to join the discussion, it is pretty meaningless to add a comment to the bottom of a page which is more than a day old.
> I think the issue isn't curation, since Slashdot is technically an editor curated news service, but the timing. That is, how do you have a good discussion when the timescales are so large rather than over the course of a few hours?
Yes! That frames the question much better.
> Sites like MetaFilter - http://www.metafilter.com/, Edward Tufte's forum - http://www.edwardtufte.com/bboard/q-and-a?topic_id=1, QBN - http://www.qbn.com/ - and numerous blogs have solved this problem to a great extent, IMHO, and intriguingly are all single threaded (or in the case of blogs, most, but not all).
Haven't used those sites, and it was hard to get a grip by taking a quick look. How do they solve it? I think single threaded is great, but in my experience it breaks down when the number of comments get too large.
Manually or semi-automatically curated discussions would probable be very valuable.
