Wow, someone's downvoting every congratulatory comment on this thread. To that guy: congratulations on not doing anything useful with your time (while we did).
Also, congrats to Josh and team! I'm totally jealous and proud of a fellow young dude.
If you're talking about those comments at the bottom, one of the accounts was created just to leave the comment, and all of them were left very rapidly after the actual item was submitted. I don't personally agree with this, but I can see an argument that they're not contributing to the discussion (and could be perceived as noise), which seems to be extremely important to some users on HN.
It isn't just "[one] guy", and I think your insult of "him" is a little bit counterproductive. I honestly don't think it's because they're congratulatory, and I think you're going after someone needlessly -- I don't see any systematic assault on good will in this thread, as a couple people have.
