Probably something like:
<a href="http://link.to.profile.invalid/me" type="text/html"
rel="me meta">Link to my profile</a>
is the best way to link to a page which contains metadata about you.
(rel=meta is formally defined in the XHTML 2 drafts, but has been
used for years by the Dublin Core and FOAF communities to indicate a
page which contains relevant metadata.)

The term "profile" used on those pages has nothing to do with
"personal profiles". It refers to the (rarely used) "profile"
attribute of the <head> element which is used to link to one or more
documents that describe the way that you're using HTML. For example:
may be used to indicate that when you write 'rel="contact"', you are
using the definition of 'rel="contact"' which can be found in XFN
1.1, and not, say, the entirely different definition of
'rel="contact"' which the current HTML 5 drafts use.
In terms of microformats, the <head profile> attribute can be thought
of as a place to list which microformats you use on the page, so that
parsers can distinguish between an intentional use of hCard and a co-
incidental use of 'class="vcard"' by someone who's never even heard
