That's interesting-- you've got 3 karma points. When I post a link, I usually add an excerpt or summary on utilitarian grounds, since I think it's less total work for me to give some indication of why other people should be interested than for a number of people to click the link than for me (who's already read the link and know something about it) to check it out.

I gather the media thread isn't a good enough place for posting links.
