Bob, the post is a good summary of the chicken versus egg problems
that are represented by standards adoption. The Social Graph API is an
attempt to help eas adoption by caching the distributed graph in a
useful form for developers to take advantage of.
rel="me" and the other XFN types are useful to avoid the 'please re-
enter all your public connections' problem for signing on to websites.

I'd encourage mybloglog to adopt this as twitter, friendfeed etc
already have.

right, rel="me" is for the subset of pages used as representations of
individuals. You can express joint authorship with hcard in hAtom, but
that is a different problem.

Wordpress already supports XFN relationships by default. I think that
adding XFN need not be opt-in when the intent of declaring a
connection publicly is clear (as in the twitter 'enter your url'
field) This is more problematic in other contexts (for example in the
FOAF SHAsum of email case, where email addresses can be leaked). The
advantage of annotating links in thsi way is that the user can already
see that the connection has publicly been made.

No.
What would be sufficient to make them ready for it in you estimation?
That will help with setting goals.
