Show HN: I made a Hacker News for everyone.

If it is the former, you ought to write some blog posts to explain how your conception is different than the current news.arc software, and what the benefits would be to this community.
If the latter, you've got the classic chicken-and-egg problem. There are known ways to deal with that, of course, but it's not an easy row to hoe.
"This is a fundamental flaw in communities on the net in general, they don't gracefully combine different scopes." - Hacker News comment by jacquesm
But to answer your question, by "graceful combination of scopes" I mean you can follow Hackers in New York (people who have saved Hackers + New York as a favorite) just as easily as you can share stuff with Hackers interested in Ruby on Rails (Hackers + Ruby on Rails) or even with Hackers interested in Ruby on Rails in New York (Hackers + Ruby on Rails + New York).
I suppose one could could argue "isn't any interface with tagging basically doing this?" To be fair, del.icio.us and the like usually let you combine tags in some way, but none of them get out of your way enough or have sufficiently simple voting mechanisms to be a really nice way to grok news. None of them implement a nice comment system, either.
This is like having your cake and eating it too! If only I didn't have to register an account to comment...
So far so good. Concentrate a bit more on the filtering/finding new topics a bit more. You could become whatsupedia.com to crowd-rated news sites as Quora is to Answers.com.
I found the UI to be rather lacking from a new user perspective. The design is nice enough, but the layout and the usage is poor and could use some rethinking.
Not sure what you're wanting from all of us here - perhaps you could let us know. Are you wanting to know if we would use it? How we would change it? General recommendations?
Ignore the naysayers.
There is plenty of room for this.
99.99999% of the population does not use HN or Reddit or Digg.
It's beautiful and well structured so that's a good start.
Now I would work with a couple of things like how you have source and comments aligned on one page, that might be giving you trouble for longer headlines. and create a more unstructured look.
Unlikely to change from using HN but I might use your site as an aggregator if you could aggregate stories from top sites (like http://alltop.com/) ... but then that's probably not what you're trying to do?
Edit: Facebook OAuth/OpenID/Google accounts are a great way to get users to login FAST.
Focus on building the community, not the site.
