I've tried many news feed applications in the past years, but I usually stick with Google Reader for the convenience and consistency, since I use Google everything. But I heard some whispers about the app Feedly, and I saw this Lifehacker post about its recent upgrade, so I decided to check it out and analyze the way it organizes its news articles.
The most noticeable principle that Feedly uses is organizing by most recent. This makes sense, since publish time is one of its resources' most important feature. It also organizes by category, which is essential for getting to the stories that most interest me at the time. Feedly also enlarges important articles, a design element used in many news distribution systems.
One aspect I like about the app is its simplicity; the format of its resources, namely the articles in my feed, has a consistent minimalist design which emphasizes content. The app is very functional; all the navigation and swipe actions are intuitive and appears to be designed to allow users to quickly find and read the articles they want to read. Scrolling through stories is fast, navigating between news sites only takes about two taps, and the pre-loading of the text in the articles lets me start reading right away, without needing to wait for the pictures and videos to download.
