Experimenting with OpenSocial

Google's OpenSocial allows one to automatically connect his identities on multiple public profile sites. See, e.g., http://code.google.com/apis/socialgraph/ .

These are a few of my identities:

Hyves: me
Plaxo: me
LinkedIn: me
OpenID: me
Bergboer.net: me

Basically, all that is needed to establish one's identity, is a bidirectional pair of rel="me" links. So, if this site points to niekbergboer.bla.com (say) with a rel="me" attribute, and that site points back to this site with the same attribute, OpenSocial will pick up the fact that these sites all belong to me identity.

Many sites, however, do not allow one to directly edit the rel attribute of a link. In that case, just add a plaintext link. Things should still work, as long as at least one link of the pair has a rel="me" tag.
