The app also now lets readers send articles to their Kindle account, saving them the step of going to the Instapaper website. And finally, the app gains support for a feature which even i can appreciate even though I won't use it: AirPlay support. You can now save a link to a video into the Instapaper app and then click the link and stream the video to AirPlay compatible devices like an Apple TV.
While apps like Instapaper were initially conceived as a way to save reading material for later, in reality they're now being used to save anything a user might want later, including videos. Video is in fact one of the more common types of content that is being saved to apps like Instapaper, and as you might recall video is the reason ReadItLaler was renamed to Pocket. So it makes perfect sense the Instapaper app to add a feature which video junkies will appreciate.
