Instagram will be introducing a new recommendations feature, which will offer recommendations based on the people you follow and photos and videos you like.
In a Blog post, Instagram mentioned this:
Our goal is to make Feed the best place to share and connect with the people and interests that matter most to you. Now with recommended posts, you can see even more of what’s being shared by our community. This test will be rolling out over the next few days. We’ll be making product revisions based on your feedback and hope to bring this to more people in the coming weeks.
