My primary email address and several secondary addresses are public in easy to find spots on the web, including my HN profile. All these addresses use gmail and I am not having a problem with spam.
reCAPTCHA's mailhide can generate a URL that the user can visit to obtain your email address. Perhaps you can post that URL in your profile. It's long and ugly though.
