Technique Reducing The Need For In-Your-Face URLs

I had been puzzling over this for quite some time, and finally figured it
out (thanks to CSS3).

Summary: Using in your face URL's is bad practise, c.f. Dan Connolly's rant
on this subject [1]. Note that DanC originally cited TimBL's discussion
about not showing the mechanisms of WWW systems [2]. The best argument for
using in-your-face-URL's was that people printing the documents out might
require the links to be shown; good point. While this is still impossible
to achieve on most older browsers, newer CSS compliant ones can utilise a
handy hackaround.

Details: Another (pre-Web) DanC citation in the same thread was:-

       "Hard-Copy Print Options to Show Addresses of Objects and
       Address Specification of Links" [3]

Well, CSS provides options for paged media via the "@media print" facility.
Therefore, crossing this with the new CSS3 display of markup capabilities,
you get possibilities such as the following:-

     @media print {
     a:after { content: " [URI: "attr(href)" ("attr(title ")]. " }
     }

Which will (theoretically) display the href and title attributes after any
HyperLink (see [EXAMPLE]). You could set up a similar system for aural
browsers as well, whereby you might want the browser to read out the URI
and/or title of a link.

I hope that this discussion will not find the bit bucket: when DanC
originally brought this up it seemed to have very little impact indeed,
which is a shame because it is a fairly valuable point. I, for one, always
used to use in-your-face URL's until it was pointed out to me that this
goes against a core Web idiom :-)
