I really liked this product (used when working at Meta). What I found interesting is that it's very similar to Facebook, but it optimizes for the opposite values. While Facebook newsfeed seems to try to maximize your time scrolling, watching ads, clicking, useless notifications; Workplace was continuously suggesting changes to maximize productivity, such as "you have not interacted with this type of notifications, stop receiving them" or "this group doesn't seem interesting to you, unfollow group" or even "set a productivity block to stop receiving notifications".
Same company, probably same underlying codebase and structure, but opposite reward optimization for showing items in the news feed and maximize productivity/time spend on feed.
