A point made is that the Y meter obscures an otherwise instantly understandable metric with a visualization that must be deciphered. If you don't care about that number, sure, it's less information and thus perhaps less clutter. For myself, it's chart cruft.
> the Y meter obscures an otherwise instantly understandable
I'm not sure I agree with that, because it takes me a noticeable amount of time and effort to look at the scores for two different stories, located at two different parts of the page, and to compare them. It's far easier to get an instant notion of how a story is performing compared to other stories using the Y meter, for me at least.
My recommendation for the Y meter is dead simple: just also show the number.
