Why can't I see friends' public and private notes combined when I'm logged in?

I signed up for pownce so I could see all my friends' notes on one page. Only problem is, there is no easy way to see public notes and private notes from my friends at the same time. I may as well be logged out, because there is no obvious navigation to get to my friends' public pages either, which is where all the content is. As a user who is more interested in keeping track of my friends' notes than posting them, it seems there is no motivation for me to have an account. Am I missing something? I tried looking for a setting to change the public notes as viewable, but I couldn't find anything.

If it is a matter of only being able to see future notes once I've signed up, then it would be great if you guys could change it so past posts show up as soon as you friend someone. That way users will feel like they've actually gotten something once they've signed up and added friends, instead of just a blank page like I've had for the last week.
