I think the red stars need to be toned down quite a bit.  I don't think they need as much visual weight.  Instead, I'd want the content titles to really be clear.

 

The advertisement block needs to be toned down a lot.

 

The Channel9 guy isn't pixel perfect around the edges.

 

I can appreciate the move toward simplicity, but something still feels a little off design-wise.  For example, the width of the Twitter and "What is C9?" columns feel off.

 

On the home page I see 3 completely different styles of horizontal rule: light grey solid, thick grey (in "Community Activity") and dotted black under the bottom headings.  This makes things feel disjointed.
