I think I'm having a hard time pulling this off because no one has yet done a good job of this.
Think of the home page of most blogs as the index, just a list of the latest blog posts.
When you click on one of the blogs, you get the permalink, a view of just that blog post.
Yet, users constantly confuse one for the other. I can count multiple times when a friend has sent me the link to the blog home page thinking that, because they see that blog's post at the top of the page, I would see it there too. Of course, they meant to send me the permalink to just that post but isn't there a way to visual distinguish these two different views?
Here are two designs I'm working on now:

I want the image on the left to be the single view. After you click on an item that will be in the whitespace of image 2, it will take you to image 1 with a vertical breadcrumb in the sidebar.
What can I do to this design to say "I am a parent" or "I am a child" respectively?
