From Dave Feldman of TechCrunch/AOL:

THE CMS
One of my favorite things about WordPress is its extensibility. We’re on the same platform today as yesterday, but have built new tools for writers and editors. Featured and pinned articles get expiration dates, so editors don’t have to go back and manually un-feature things. Selecting a post layout is as simple as clicking a button. Automated resizing of images means faster load times and fewer distorted photos. And choosing which articles go on the home page is a single-click affair.

Impressive work by everyone involved. More details on the announcement post Redesigning TechCrunch: We Picked This Logo Just to Piss You Off
