Well, couldn't I just put the links in my entries manually? Edit the HTML myself? Yes, I can do that. I can also bash my head between two chunks of cinder-block, but I won't. And couldn't I just list the names of some sites and let the readers go to them on their own? Uh, yeah. But first off, I have no readers, and second, I haven't seen anything I want to waste a hypothetical reader's time with.
