Since this is more involved, I'm putting it as an answer even though it's in support of the original idea.
I realize that the links in the "about me" box are nofollowed. This is often understood to mean that they are only for real people browsing, and that search engines are supposed to ignore them. What it really means (at least according to google) is that your site doesn't vouch for the content at the other end of the link. It still may get crawled, and may get used in ways that don't affect your site.
I realize that my "website" link has the property, and is not nofollowed.
The reason I would like to be able to use
rel=me in my profile is a bit complicated. I link to SO from a number of different profile sites (most of which are dofollow), all using
rel=me. Because anyone can link to any site with that attribute, crawlers know that both ends of a link should be validated before they can count a profile as confirmed to belong to the "me" that the web of other profiles create.
Unfortunately, not all crawlers are perfect, and sometimes miss pages or simply aren't interested in crawling an entire network of profiles. There are user agents who simply look for the 2-way "this page links to that with
rel=me, that page links to this with
rel=me". In those cases, being unable to link to more than one page means that my SO profile must stagnate as a leaf rather than as an interconnected web.
I'm not asking you to change the nofollow policy. Just allow us to add
rel=me so we can confirm ownership of our profile in the context of multiple inbound
