Now all we need is a 3-D style phase-space animated gif series, which reads off the mix of responses...maybe one response, no pic.  A couple of responses, you see a simple design (have a few in there to stop it all becoming--irritating--) and as the ratings mounted up the design would become more complex...

The trick is...you can't easily find out the ratings--unless you posted the comment.  All the others can see are simple or more complex shapes, developing over time.  But if one has access to one's own ratings, and can see one's own shapes, one will learn what the shapes mean...but they will never have a binary meaning..once they start up, they're endlessly flexible (two "4" ratings, for example, would give a relatively simple diagram in, say, five variations...so once you've seen all five you get the idea...but a comment with fifteen ratings on two (or three!  No!) different scales...and raters could choose how many scales to rate on...oh my word...

I'm scaring myself.
