I like the simple UI. Here are a few ideas that came to mind while trying it:

- Ask me to choose a few categories before I start so you can do better news targeting and get me more engaged right from the beginning.

- Going through stories need to be faster. Either pre-load the next few stories or show me a list of headlines on the side so I can skim through and click the ones that catch my attention.

- I need a back button. A tiny link would suffice as I won't be using it often, but when I need it it's very useful.
