I'm really happy that HN isn't your typical constantly-mutating, constantly growing news site, adding a new social share button and 2KB of new Javascript every week. Please, pg, don't start taking pull requests or anything like that, it's great the way it is.
Edit: look at the current top story. A pretty but not especially functional Facebook redesign, proposed as the latest in a long line of changes that the users pretty much always disliked. There's my point.
