Instagram looks to add yet another function to their app with the introduction of Instagram Direct. Similar to popular image sharing app Snapchat, Instagram Direct allows users to share photos and videos to a select group of friends, family and followers. Whether or not this dilutes Instagram’s identity or adds to it remains to be seen. You can try it for yourself, though, as Instagram for iOS 5.0 is now available for download in the App Store, while Instagram for Android version 5.0 is available via Google Play. Instagram for Windows Phone is in beta.
