I think limiting to HN users is good. Given HN is a free community, it might be nice to see some HN information about the user (who they are, how long they've been a member, links to posts/comments, karma, etc). If I'm crunched for time, I'd probably be more willing to help somebody who is making HN a great community in favor of helping somebody who joined 35 minutes ago to get free consulting. (Note: Unless abuse occurs in the future, I would prefer to choose myself rather than having a policy that says "You must have XX karma or be a member for N months.")
