Instagram will test adding suggested posts above posts from people users follow.
Instagram claims the reception to its "suggested posts" feature has been so positive that now they are testing mixing suggested posts throughout your primary feed, including ahead of posts from people you follow. This signals that Instagram is shifting to becoming more like Facebook where the algorithm is in control even though people might prefer to just see posts from the people they follow. People are still upset the feed is no longer chronological, and now it will include posts from strangers. Link
