Everything from twitter to reddit to hacker news to metafilter works, essentially, as a comment forum where discussion is on “another tab” to the original URL. It’s the default nature of the web – one thing hyperlinked to, rather than appended to, another.
This is why I’m convinced that these problems are local UI problems (e.g. hidden links from BB posts to BBS at one end, and the ugly auto-posts that start discourse threads at the other) rather than issues of fundamental healthiness.
