If you can take the productivity hit to do this, I would be interested. My preferred format is kindle/iPad ebook of some kind, although PDF is fine too. I would pay up to $20/mo, but $5 would be more fair. (I figure I'd save 5-10 hours a month, with only some loss of quality). It's like methadone for a heroin addict.

I'd also appreciate a hackernews-to-rss which actually embedded the body of the article AND the comments, which you could maybe do as a related service. If it were properly paginated to work well on various mobile devices, especially synced to work with no online connectivity during reading, it would be great. iPhone, Android, iPad, Kindle would be great targets.

I think ignoring copyright is the way to go.
