I actually really like the Y-meter, though I'm not a fan out completely hiding the numerical rating of the topic. It might be worthwhile to still show the number for those who are curious.
I agree. Actually, showing the number inside of the meter would be nice. I also agree with another commentor, oftentimes im after the comments link, dont stick it on the other side of the page. Id really like the ability to click one link that opens the source and the comments at the same time (RES adds this functionality to reddit for instance)
