Instagram has been experimenting with a new test feature that allows users to post updates collaboratively. This will be possible in both the main news feed and Reels.
These will be easily distinguishable as they will show two profile bubbles next to the post, making it clear that it is a co-authored post. This will also allow both parties to have access to stats and a single stream of comments.
This is an interesting new addition and one that could help maximise engagement as well as broaden reach. It should also allow new collaboration opportunities for brands and influencers.
