Because it overrides the page itself you can't click "Back" or Alt+Left or whatever to go back to the list of stories. I did go back and add the check for if I'm already inside the frameset to my code though. Gotta prevent those recursive split views :). Now if you surf back to the main page in the right frame and click on a SplitView link it will reload both frames.

I will look at it in Safari some and see if I can figure out what the deal is there. Safari's Activity window doesn't show any errors.

I'll also see what I can think of for the Back button issue when doing it your way. That may not be a big deal to anyone else though.
