OK, then why can't
http://en.wikipedia.org/wiki/Steven_tyler
just do a browser redirect to
http://en.wikipedia.org/wiki/Steven_Tyler
As the URL you leave in the user's browser location bar is the one he
will tell all his friends to use. You can't expect him to
be smart enough to dig the canonical one we would rather he use out of
all those links on the page, even if it is "right there linked to
'Article'".
