Unless I'm mistaken, that would have happened only if they were piping 
all external links through a script and appended the actual destination 
URL as a GET parameter. With some very simple URL rewriting, you can 
make each link to an external site unique (at least within the context 
of the site) and keep the whole visited/unvisited thing working just fine.
