They're a good substitute for sending photos via texts, or using Snapchats that quickly disappear, because the messages are saved in your Direct folder. The system is also less confusing, because it saves comments between you and your friends in one thread, instead of multiple threads, similar to the way text messages work.
Use Instagram Direct to send profiles, location and hashtag pages
The new Direct features also make it more convenient to suggest accounts, hashtags and location pages you think friends should follow. In the past, people would send these things via links or screenshots. With Direct, you need only tap that curved arrow icon.
If you're looking at posts under the hashtag of #summer, for example, you can send the page to friends by clicking the curved arrow in the top right corner of the screen. The same is true for location pages. To send a profile, you tap the three-dot symbol in the top right corner of that profile page, then select "share this profile" and choose the friend you want to send it to.
