Assuming you start your reading on page with a blogroll (or just a page with links) you can use the new SnapBack (also Option+Apple+P) tool to jump back quickly and pick another site to surf. You can also choose to mark any page for SnapBack (Option+Apple+M). Dig it!
Hopefully the Safari team will pay attention to our feedback. I have already suggested the addition of Tabs, the use of Keychain for password management and Form AutoFill.
