Sometimes I think it would have been quicker if I had written my own web logging software. This time, I have spotted “Read the rest of this post” coming up as link text for different targets. Can’t blame WordPress entirely, as this is actually something that seems to live in the themes.
Fix for the Letterhead theme and derivatives (and probably Kubrick): find the line in post.php with the link containing the_content(). Change the line to something like this:
< ?php $thist=get_the_title(); the_content("Read the rest of $thist »"); ?>
