Interesting, since this is one of the feature that I had abandoned. I thought that such a feature would needlessly be a bit too aggressive if you get what I am saying.

Nevertheless, in the "custom styles" input in the popup, you enter the following to blur out all points, comments etc:

  span.score,
  td.subtext a:last-child {
   filter: blur(3px)
  }

He is saying you can already do what you want to do. His plug-ins let you add custom styles. The place where the custom styles go is inside a text box that appears when you click on the plug-in's icon.

Just copy the style he provides above, paste it in the custom style field, and it will blur the "integer counts" just like you asked!

Thanks for explaining :)

To clarify the actual question asked:

What did you mean when you said it would be too “aggressive, if I get what you’re saying” - which I do not.

(Also, that CSS exposes a coding bug in the HN site re: counts, at least as of a month ago when I last tested something like it.)
