Well done on the NoScript front. It's rare to see a site on HN that requires JS and falls back to a nice explanation of why it needs JS (Instead of just stating the fact, or worse, displaying a white page).
I just checked my comment history and about 50% of my comments have been related to this issue. This is the first one that is complimentary.
(even for those who think noscript browsing is not with the times any more, it's still good practice to give a decent error message / explanation instead of breaking or blanking)
