What you find by scanning for high-point comments is not necessarily insightful stuff but rather, most upvoted stuff. Then you upvote it, making it feature even more prominently on the page. The comments that you didn't read, no matter how insightful, get no points from you so they fall further down the thread. I've seen this happen, joke comments positioned very high while truly good comments are very low because nobody had the patience to reach the bottom of the page, read them and vote.
