Don't worry about it and it's all good. HN is self-balancing. I've been here for 884 days according to my profile, and I've always been hearing these worries since day 1. Somehow, thankfully, HN works. It has not turned into Reddit, Digg, or MySpace regardless of what people say. Yes, it has changed over time, no it's not a worse place.

Yeah, kind of thought so--a little diversity can be refreshing imo. I noticed that HN redirects you to a previous submission if you use the same url. Perhaps the same could be done if you post something with the same url used on a previous reddit or digg submission.
