Any time I see something valuable on HN I quickly bookmark it so that I can read it later on without the hassle to search it. Search is a hassle on YC. I think we need a solution especially having been used to quick and effective google search for almost anything.
In a sense, HN is itself a bookmark site once logged in. That is, by looking at the "saved stories" link from my profile, I see what I've upvoted. Hence an incentive to upvote not just good items, but items I want to look at multiple times. (No such "saved comments" index exists, though?)
I compulsively bookmark anything interesting I read on the net these days. Nothing is as annoying as wanting to refer to something I've read before and only able to find it again after a huge googling effort.
If it was trivial, there wouldn't be so many questions about how to search the site :) But thanks.
Edit: Or maybe if you're the type of person who can't figure it out, you're not the type of person who should be posting on HackerNews in the first place?
Anyone that has content that's interesting to hackers is "the type of person who should be posting on HackerNews". I love this community (and hacking in general) in large part because it's not filled with that sort of elitism; anyone who's able to contribute in a positive way is welcome.
For convenience it should be a box with a button posting to searchyc.com, it's much better at searching HN than google. But something is better than nothing.
