Minimalist Blog Rebound

Here's a mockup (full) of the blog I'm designing for a client. Feedback is welcome!

As before, social icons are the rollover states. Drop shadow won't be shown fully until the browser has been scrolled around 5px down the screen (will fade in). Also changed the AIM icon to a blue hue to increase visibility, but also maintain one of the colours that AOL uses on aim.com.
