I don't think "old users" is a good metric for measuring quality, it assumes that the age of your account is somehow related to your intentions on this site. There's 3 things I think are affecting the quality: 1) A lot of stuff is written specifically targeting HN, that probably didn't happen when the traffic a front page story got was negligible 2) There are sites that blindly submit everything they publish 3) There are people who blindly submit popular sites within seconds of them publishing anything You don't have to be a new account to be doing any of those things. My account's ~4 years old, I could be doing any or all of them.
