I wouldn't change it a bit. Especially feature creep is deadly for a community. Simplicity is key to the current success of HN. I've been on Mixx before and they really messed up the site in the course of a few months of perpetual changes and adding new stuff all over the place. In the end you have a myriad of features nobody uses and the most important things Mixx was designed for initially got buried below those. HN has a clean straightforward, no frills and timeless kind of design and functionality. The only thing I'm missing is to be able to display my submissions in a row without the pages I voted for.
