Just put out an update on the database to correct the missing icons. As channels change icons the old links go dead. Should be back to near 100% icon coverage now.

As far as "elements out of focus and missing some borders" goes, I think this may be referring to the choice to have channel descriptions pop-up on hover in the lists rather than cluttering the screen with text. It may be something else, we do use a gray background underneath the page headline (with the channel title, subscriber count, large red "View on YouTube" button, and channel icon), for example.

Of course, we'd love to hear more feedback on the page design choices.
