Ask HN: Critique my minimalist rss app

I never got into using a dedicated rss reader, but the death of Google Reader and iOS7 coming out soon, I feel like the market can handle yet another rss reader.

I decided to take a 3 day break from my usual projects, and wrote my own iOS rss reader powered with a Node.JS backend for parsing users feeds. What I really like about my implementation is the intuitive swipe gestures for marking read/ favoriting articles, and a ultra fast tap and hold preview mode of articles (no network connection needed).

I would love to hear some critique on the idea/design. The plan is to have my friends play around with it later today, and release it to the store as soon as its approved.

EDIT: Forgot to mention, there is also a Google Chrome extension I am working on as a companion to the app to easily add more feeds, and track new articles on the desktop.
