i like the design - i don't think the animation adds much though. For all the stuff that's going on in the world and how the other aggregators behave, i think that just 5-6 stories showing up is not enough when I click sometimes. Your categories are a little weak "Lin" shows up in news of the World, Apple shows up in National. Keep tweaking - there is definitely room for a better news aggregator and being able to easily switch to other national editions is great!
