The comments with a 'high' rating I read (whatever high means) and then I move on.

And quite possibly get a status quo viewpoint confirmed while failing to ever find the key points that challenge. Unless you/we know quite what the system is usefully measuring, if anything, then there's little point in using it. Especially if you use it to just pick the posts to read, as you lose the thread context of the argument rendering it all pretty meaningless.
If like me you don't have the time, it would be best just to read say the first 5 or 20 minutes worth then move on.

I think the points made by Noizette and many others are sound and have not been debunked and it would be best to dump this innovation, with all thanks to SuperG for the efforts all the same.

Well Richard I see what you mean....I also don't read everything, there is too much, one needs to sort the chaff from the wheat.. etc. I guess this comments rating thing just sticks in my craw, for personal reasons, I'm a teacher (weaker students..etc.), some kind of socialist (workers committees and so on), been active for minorities (the right to have a voice), live in the most hands-on democracy, etc. etc. So it irks me personally.
