The app looks promising but you'd have to show a bit more before I create yet a other account.
How much research/interviewing did you do before building the UI/UX? I ask because I'm curious to know your findings, e.g. an outline style expandable list of stories performed better than the magazine style that was popularized by Flipboard.
Also, is there an easy way to collapse similar stories. I hate reading the same story about Apple 10 times from different news sources (not picking on Apple, just as an example).
