I'm sure there's more that could be shared about how "wants" were determined, which would counter my off-the-cusp thought here, but anyways:

Yes... my ideal would be for facebook feed to be a once-a-week addiction (maybe a bit more) where I go, see what's new, and clearly hit an end point where I know I'm seeing things I've seen before. But I'm also part of the "problem" in that I post myself maybe twice/year now.

I'd suspect the current doomscroll-y feed like we have now/you were working on reduces my likelihood of "interacting" with friends' posts. "Do I make the effort of commenting, or lazily keep scrolling to the next-often-good 3rd party content?"

A year or two ago, I copied some greasemonkey type script off reddit, and that nuked all the non-friend content off my feed, but that stopped working a couple months later and I haven't been strongly enough motivated to find an updated approach. I have little enough friend activity that I'd easily notice when I hit old content.

The current doomscrolling feed of algo content sure does manage to hook me, so that's a nice indicator of the current team being successful :P
