I really wish there was a way to save a link for later reading without up voting. Sometimes I'm on my phone, see an interesting title I can't read right at the moment, but feel weird about upvoting it without actually reading it first. I've tried using read-it-later apps, but that works mostly for the articles and not the comments on HN which I find just as important.
