I downloaded it. Nice. Some quick feedback:

1. It looks like you are querying out real-time to bring back the list of stories. Why the need to modify/delete SD card content?

2. The default action, when clicking on a news item, is to take you to the website of the article (or here, for ask). You have to long press to see the comments. I hate to say this, but I often read through the comments BEFORE going to the outside link for the story details (ask is the exception). Can you give a preference of what you want to be the default option when selecting a news item?

3. Nice touch - to put the icons of the website (e.g. blogger) next to the article title. Hard to see, but still decent.

Anyway, nice job!
