"Instead of sending each other interesting articles, they could just see what the other person was looking at and start their discussion there" Isn't that what Delicious was? (http://www.delicious.com/ http://www.delicious.com/) "Keep, share, and discover the best of the Web using Delicious, the world's leading social bookmarking service." So instead of saving the good articles you find to share with your friends, you are going to save the whole process of looking at the non interesting stuff and then finally showing your friends the good articles? I personally like it when a friend of mine sends me a link to a news hacker article or anything else instead of telling me the process of how they got to the end result.
