Okay, I've been using it throughout the day and here are some thoughts.
I still like it. It gives a nice selection of categories and sites to choose from. However, the "Latest" tab I find is a bit weird in it's design. It'll only show 2 news at a time, and you cannot scroll through it but have to wait for it to go through the sections by it's own rate. I'd prefer a design more similar to that of the WPCentral app which gives very easy access to new articles. I admit this may be awkard if you have many categories but the design is not quite efficient yet. Furthermore, a lot of space is being used for nothing really in the top, bottom and left side which makes the design feel a bit "compressed" if you will. The icon is quite nice btw.
So all in all 3/5 - great potential and and easy to use, but the design and some parts of the functionality needs some more work. I will continue using it and hope to see some future updates.
