because there are none.

(on Facebook core product)

I am leaving out their never really widely launched crypto hype disaster of a product on purpose.

Really? Facebook Events? Groups? Marketplace?

These are pretty major, successful features that drive a lot of use.

Those features drive use but did they also increase profit, given that Facebook successfully enshitified their main product (the news feed)?

I don't disagree with your main point, though: Facebook certainly developed lots of new features, whereas Twitter pretty much stood still.

I don't have any insight into groups, but I do into Marketplace where yes it absolutely did.

I'd be astonished if Pages didn't have a measurable effect too since they are one of the main ways brands (which is a major source of FB revenue) interfaces with FB.

Some of the things they have launched:

* Facebook Apps (not really a thing anymore. Maybe it still exists)

* Facebook Games (remember Zynga?)

* Facebook Deals (they were taking on GroupOn)

* Messenger (as a separate product. One of the most heavily used products in the world)

* Events (which for many people is the only reason they have an account)

* Facebook Groups (still heavily used)

* Facebook Pages (still heavily used)

* Facebook Video (still heavily used)

* Facebook Marketplace (extremely heavily used in many markets)

* Stories (still heavily used)

* Reels (sort of merged into Videos)

* Facebook Places (big plans, but died)

* Facebook Graph Search (nothing like originally released: https://en.wikipedia.org/wiki/Facebook_Graph_Search)

Don’t forget the Facebook phone!
