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.
but think about it from a different perspective: there is a feature that many people agree would make the site better. e.g. a new job board for non-YC-companies, like discussed here: http://news.ycombinator.com/item?id=4993571. lets assume that after openly discussing the problem, pg and the majority of the community agrees upon a solution. now lets assume that there are more features like this, and that pg hasn't the time to implement them all. wouldn't it be nice if the community could help out?
