I would encourage people like yourself to put enough information your HN profile that you can be reached for networking purposes by other HN readers. Many of us may be in a position to offer interviews for non-suck jobs or pointers towards same, that we aren't going to post in open comments to the entire HN community, but would send targetted to the email in your HN profile.
If you are shy or anti-marketing, you may need to work just a little harder in mediums you are comfortable with to network. (This isn't directed at you specifically, MC.)
Seconded. I'm hiring and whenever I see HN posts I like I check profiles immediately for location information and contact details, or at least info on where I might find out more about someone.
You now have location there (which turns out to be fairly close to one of our facilities) but no contact information, so I still can't reach out to you.
If you're extremely uncomfortable listing an email address (or lisp form that evaluates to one or something similar), you can reach out to me based on my profile, but I'd really urge you to list some contact information in your profile, even if it's a throwaway account that you can easily walk away later from if the volume becomes overwhelming. If you're reaching out to me, add "HackerNews" in the subject line, please.
