IANAL but... I don't believe your issue would be with HN. HN is just an aggregator for content published elsewhere, so they have no say in whether or not you also link to that content. As regards wanting to publish 'interesting threads', by which I assume you mean debates in the comments; again, I wouldn't worry too much re HN themselves. There are no T&C's to be agreed to when you register an account here, so no-one who comments has granted HN exclusive rights to publish, or transferred copyright on anything they write here. Nor has HN asked for, or claimed any such rights. So, if I hereby also grant you non-exclusive rights to publish my ill-informed drivel elsewhere, then that's a matter between you and me. Nowt to do with HN. Of course, in theory, this would mean that you'd have to satisfy yourself that anyone else who comments here and whose words of wisdom you want to reproduce is similarly amenable –and there you open a whole different can of worms, as regards whether or not a comment published on the intarwebs, with no copyright claimed or given, is in the public domain, or not. I would suggest it [at least partially] is, as is borne witness to by the common practice of reproducing other people's tweets, as practised by most news websites.
