I'm a convert. I last voted to display scores, but now I think hiding them is best.
The reason is because HN was (is) becoming more affected by the same cycle we've seen play out where content from a small set of users which reflect core site values makes the site good, but this draws more attention and users until content quality begins to suffer; quality posters leave, and find some new site which starts the cycle again.
I think leaving off the comment scores is the only way to check that unwanted behavior. We have to deal with the inconvenience of not relying on scores to skim comments, but I think that can actually be a good thing; I think that's just HN at a new (more sustainable) maturity.
