Soundcloud comments seem more like Twitter-style one-liners than an actual discussion with replies etc. I actually find some of the youtube comments amusing; for example, the comments following the Russian dash cam videos and other such weird-but-true slices of life.<p>Internet communities are a work in progress. Reader comment/talkback/forum plugins are considered a necessity, and yet much of their content is pointless and trivial.<p>Hacker News does a pretty good job, for some reason, maybe mostly because of the ferocious moderation of anyone who strays from factual and reasonable sorts of statements into ad hominem or pointless sorts of space wasting.<p>But most sites are terrible. I guess the only solution is heavy moderation and a core of reasonable folks.
