Interesting thread you've started here.  I guess I'm a bit clueless, because I don't follow the charts, nor do I submit a rating when I comment.  I comment because I like something enough to do so, the C&P-ers will just find another way to get around if they fix that one.  I see it all the time in Photography, where I do most of my posting--pages and pages of comments on the most banal of shots, simply because someone comments on just about everything they see.  Oh well, I'm here because I love doing what I do, and if someone wants to tell me they like it, I'm up with that.  If they don't, that's ok, too.
