This is going in a great direction, everything worked form me.

I would like to suggest a future direction: be inspired by the Windows 7 Phone and Playstation 3 interfaces and make different branches for different topics. For example, All tech stories would be on the right of the centre, all current affairs stories would be on the left of the centre and pressing some button would bring me back to the beginning; better yet would be if there was a simply a grid for website types, so all stories along a particular line would be of a particular field and the user could customise this and moving arrows up or down would change website type.

Check out the BlueBottle OS (A research OS at ETH zurich) that a zoom based window manager. A video can be found here: http://www.youtube.com/watch?v=Pe0ZdzO_urU
