An observation about the disappearance of karma on comments, is that in searching older threads (I'm currently looking at a more technical thread ~1000 days old) is an inability to distinguish between the utility of comments. E.g. if there is a solution set of A,B, or C to a particular problem or question, it's impossible to tell if 20 people thought A was a good idea while B and C were both 1 point answers. Maybe threads past a certain date threshold could display these vote counts?
