I hate creating a new profile every time I go to a new place on the web.  Even worse is that when some of my information changes, like, say, my job for example, I am in update unhappy place. 
    Wouldn’t it be cool if there were a way to create an RSS feed of my profile and "about" information?  Then I could give the feed of that info to each site I maintain a profile with — and every time I changed the info in one place, it would get changed in all of them.
    Has anyone done this, and I just missed the memo?  I know OpenID is a protocol for login stuff  — but I don’t see it working in the way I’ve described.
