Direct messages from strangers require extra step before receiving
Following a general rumble of expectation for weeks, Instagram has just launched its own private messaging service. With the latest update to version 5 of the app, you can now send images and videos directly to individuals and groups rather than your entire follower base.
You'll be able to select where your image goes — to "Followers" or "Direct" — after you've taken and edited your picture or video, and if you select Direct you'll have a choice of sending to just one or several people you choose. Once sent, you'll see an indication underneath the picture of who has seen and liked the photo, along with a standard Instagram comment thread underneath. It's the same Instagram experience you know, but with a smaller audience.
You can go straight into the Direct portion of the app with a new inbox button in the top left of the home screen, where you'll see both read and unread messages, along with "Direct Requests" from people that you don't follow. The latest update is already live in the Play Store, so have at it.
