> I'm not a product manager - but I can't imagine one sitting in a room thinking about all the evil ways to make the feed harder for people to find relevant posts. Increasing "time spent" means spreading out relevant posts. I'm sure that Facebook is tuned to optimize for some combination of "time spent without drop-off in engagement". This is a "Good" version of the algorithm because it nets them the most revenue, while still fulfilling the need for the larger user base. It's milkshake marketing[0]. People don't want the most efficient method of content consumption. That's why most "feeds" are no longer chronological. People on Facebook want to scroll around, look at posts, comment on articles, like a few things, etc. for X minutes/day without seeing things they've seen before, and without seeing things that are boring. The job-to-be-done isn't to consume a certain relevant piece of content, it's to waste time and not get too bored.
