Ah, that isn’t what I’d call a blogroll. That’s what I’d call a series of blog posts.
Whatever you did for “THE EVOLUTION OF CELL PHONES” doesn’t work for the other of your blogs posts?
If not, you will likely need to change the template file so that whatever it’s doing for the first does similar for the others. I’m guessing the template does them differently because having them could make things a bit crowded.
