[HNPoints]

Thanks for the tip! Given how technically savvy most of HN is, I was thinking the XPI download would be sufficient at least for now, but when I do go to submit it to the addons repository, I will be sure to put the actual JS in there.

I am indeed using the Chrome extension, but it only updates comment scores every 10 minutes while on HN as not to slow down the HN reading experience. :)
