I actually considered posting this idea just now too, but since you did, I don't have to. A javascript +/- button to collapse and expand threads would be perfect. The indentation is just too subtle, and it's too hard to follow the thread in bigger discussions (which are often the good ones worth following). Somewhat unrelatedly, I would think that comments should get extra points if they spawn a lot of discussion. I mean, that's what the points are for, right? This would credit the original user's karma for fulfilling the goal of the site, but more importantly, it will bump up the entire discussion higher on the page to better reflect it's value. (Though I don't know the algorithm that orders comments, so that part may already happen)
