The ability to pin posts is really just an expansion of the pinning feature that already existed on the platform. You could pin Stories already, and now, you can also pin Reels or posts.
This feature also makes the process of pinning easier, and is very much akin to what about TikTok and Twitter allow users to do with previous posts that they have made.
