I am looking for some feedback on my new "visual" bookmarking site

It's called Klipbook and it allows users to store and share notes and links with rich multimedia.<p>Here's an example account: http://klipbook.net/brainfilter/<p>There's a lot of functionality I'm planning to include, but I figured I should start getting some feedback now that I have built a "minimum viable product."<p>http://klipbook.net/user/register.php
