I built a HackerNews firefox extension a few days ago to monitor new comments directed towards you or your submissions which you could port pretty easily to your site if you were interested. Or if you build an api to a users threads/comments (need just be an RSS feed) Id port it for you if you wanted it.

You can grab it here: http://wildstabmedia.com/hackernews and just save the xpi to disk and unzip to get at the source

Thanks for the link, it is interesting. I think I am going to opt for the rss plan.
