For those who may not have registered this, on those posts which have a “Read More” link at the bottom, that isn’t a link to the post page; rather, if you click on that, it will display the whole post right there in place on the main page of the blog. The guy who developed this calls it a “Peekaboo” link.
Thus, for instance, if you’re on the main page of the blog, you’ll see a “Read More” link just below this; if you click on it, you’ll see the rest of this sentence appear in place. Click on the “Summary only” link to return to the shorter display form.
