Would you elaborate on this, in particular what you mean by buried? I'm assuming you're referring to 'spangry's responses. Given the nature of threading and where 'spangry chose to respond, I don't see how it could be anywhere other that where it is. As of the posting of this comment, both of 'spangry's responses are the highest of its siblings. Are you thinking of a different model of threading or highlighting highly-upvoted comments?
