Do you mean an instance that is tied to and moderated by HN but distributed to handle a bigger load, or a completely stand alone website where I must moderate it?

If distributed I might consider it. If it's just my site probably not. If it's my site I would have to pick topics that are not covered by HN and most of the interest here I have seen that is off topic is politics. That would mean I have to set up a site that can take a serious paddlin' which I have done and it's a lot of work. I'm lazy(er) these days.
