A few practical suggestions: Many people here have contact info in their profiles. If you find a good (dead) comment thread, you can contact the people involved directly. I suspect many of the people here would be willing to continue the conversation. The other way to restart discussion is to repost (if the topic is more than a year old). That's a pretty common theme on HN. You can link the past discussion in the comment section for context.
