The Magazine, created by Marco Arment and executive edited by Glenn Fleishman, has been updated to version 1.2.2, but don't let the small increase in numbering fool you -- there are a couple of great new features contained within it (and not just the story kind).
First and foremost, with the new version of The Magazine you can now "Write Letter to Editor". Similar to the traditional newspaper and magazine system, Arment and Fleishman say:
We'd love to hear from you, and we may publish your letters in future issues.
Also added is support for Gmail and Sparrow, so you can use them to send your letters, or share via email, if your prefer.
Since iOS doesn't currently support anything like intents or contracts, or provide the ability to set third party apps as default, it's up to developers to work that out on an app by app basis. And it's great to see Arment doing just that.
The Magazine remains one of our favorite reading apps for iOS. If you haven't already, it's free to try and, if the subject matter interests you, easy to subscribe to.
