This is off topic, but I recognize your username from a thread a couple weeks ago but your account is relatively new. Out of curiosity did you just find hacker news and decide to make an account, or is this a new alias and you have an older account? I guess I'd be surprised if there's still new people joining lol.
I have no idea who they are, but I think you'd find there are lots of "old-timers" (even notable ones) who've never had HN accounts. Any of them could decide to join at any moment
