I think the reason you get so many repeated posts from newbies, is that HN does not have a search feature. I think simplly adding a google search to HN would likely cut down on this issue.
SearchYC is often really slow, at least for me. The page loading times are on the order of tens of seconds. HN needs its own minimalist search engine designed to search for submissions.
I'm working on a solution for this, but ultimately it comes down to hosting costs. SearchYC is currently hosted on a cheap-ish virtual server whose costs come out of my pocket each month. I can't justify spending more money on this project, given my personal financial constraints.
Traffic has been steadily increasing, and quite simply, the system can't handle the load at peak usage. I am, however, working to resolve some of these issues, but it may still be awhile before you see any improvements.
Indeed. Unfortunately, though I know about searchyc (because I've been around here forever), it's not very discoverable, so newbies haven't a chance. There is not, as far as I can tell, a single link to it in the HN menus.
Incidentally, Paul was working on search around this time last year. I wonder what happened to that.
