In general, reading an interesting article on a site you've been linked to and then leaving the site without reading more seems to be the default behavior for humans, unless the article in question has particularly interesting links. Since most sites have a lot of variance in the quality of the articles, this is pretty reasonable behavior: only reading a site when somebody bothers to link to it will increase the odds of you not wasting your time. It often takes several links to the same site before you get interested enough to actually start reading it.
