But even with a single thread you’d have the same problem. How would you know what’s useful beyond using votes and sorting?

I wish I could set multiple sortation options at the same time. So I might see the top 'best' post, followed by the top 'controversial' post, followed by the 'newest' post. Then the second best of each.. etc..

As for threaded, I like how StackOverflow handles this. You have separate top level answers, but underneath that is flat comments that can be filtered a tad for quality or totally unwrapped. That system works very well.
