MUST is pretty abhorrent to me. I use rel="me" on my blog, which
is also my OpenID URI, which is a very strong way of my attaching
my OpenID to my flickr, twitter, del.icio.us, pownce, etc profiles.

One of the strengths of XFN over FOAF for me is that it separates
the concern of expressing a relationship from that of providing contact

I don't see the value of the hCard in this scenario, a URI is a great
way to identify someone:

I can see valid use-cases where the URI being linked is sufficient.

Yeah, backwards compatibility with XFN as it stands now.
