> you have seen it all, go outside
Or "you've seen it all. Bored? Click here to let your friends know you're looking for something to do/see who else is bored". Or "Bored? X needs volunteers!" Or some other positive suggestion to try to prevent a "eh guess I'll doomscroll something else" reaction.
Isn't this what ancient local BBSs did? Back in the 90's when in my teens/twenties that was how I found interesting local groups of people/organic raves (i.e. not ones organized by promoters) outside my established circles in Santa Cruz/the bay area. Also some of the most uncomfortable/awkward unsocial/nerdfest social evenings so not everything was a hit.
I'm guessing that there are now Discords that fill this niche?

"Alice, what if we made a button that improved overall human wellbeing, while somewhat reducing our ad-revenue and lowering the engagement-metrics we use to sell shares to investors?"
"*sigh* We've been over this, Bob: We only build features for customers--not cattle."
That would be such a killer feature. And it could find other friends in the area and that are also free. Not like Meta doesn't have some kind of model for all that data already probably.
