"something 4 people use every 6 months doesn't tend to get optimized much"

Yeah, but the usual case is still to throw stuff like that on a spare "random odds and ends go here" server, not a production one whose performance/responsiveness you care about.

It likely has a dependency on HN: looking up users, karma, etc., which is just simpler to do on the same machine.

Ranking applications by HN karma? I hope not.

They've been clear that they do look at your HN posts and comments, etc.

It may or may not be used for ranking in specific, but it's definitely used and they've always been upfront about that when asked.

Also, they use hacker news to communicate to applicants. I applied a while back, and one day while browsing I got a message through HN, something like "pg has a question for you" in the header bar. Clicking through is the question, and place to put the answer.

Basically, there's a whole messaging system in hacker news that most people don't see.

Yeah, this is known :) but an algo that incorporates HN karma wouldn't be the best thing :P

I was told once that they don't rank on karma, but if they recognize your name from discussions around here it helps your case.
