Regarding your "Theory 3: It’s Not An Entirely Efficient Design" I usually go through a few pages of Hacker News and open anything that looks interesting in a set of tabs. If the article I've enjoyed reading happens to be of from a page of Hacker News that I no longer have open, I probably won't look for it within HN just so that I can upvote it. It'd be nice if there was a Chrome Extention or something that would let me upvote the HN article.
