After trying a non-adjustable standing desk that I built for a period of two weeks, I came to a similar conclusion. It initially felt pretty good, but after a few hours had passed I ended up taking a lot of breaks that I normally wouldn't have, simply because my legs couldn't keep up.
Also, my feet were in some serious pain for the first few days, even with a thick floor mat, and continued to lightly ache afterwards.
I always just bookmark the comments, or a link to a particularly valuable comment, instead of the actual page for the same reasons.
I have a separate folder for the actual pages that I link with their corresponding HN bookmarks using Firefox's tagging feature. It makes it easy to find and load up both pages.

After all, you're targeting users who, even if they aren't incredibly informed, at least have enough technical savvy to be running a site.
