I too am not really worried about the site. I haven't been around as long as some, but I've noticed more than anything that topics about startups that used to be exciting are now getting stale. We've learned new things from HN that leaves us looking for more and we aren't finding it yet. I trust in the community and those writing about technical topics to keep pushing the limit and teaching us new things. I don't want to see the mechanics of HN change too drastically.
