You can create a Google Profile, and add all twitter, facebook etc. links to that profile. Also you can add a link to the facebook page with rel="me".
"If you host user profiles and allow users to link to other profiles on the web, we encourage you to mark those links with the rel="me" microformat so that they can be made available through the Social Graph API."
