Adam Mosseri on the gap between what users say they want and what data shows they actually prefer.

“One that comes to mind is kind of this transition everyone eventually goes through to this broad global feed. everyone it always feels like people think I just want to see chronologically everyone I know and follow and that's going to be my favorite feed and it continues to be proven wrong.

Why social media algorithms are less semantically sophisticated than users assume: they rely on illegible embedding vectors, not detailed models of user interests.

Instagram's heavily protested feed redesign was never actually planned for launch, it was only an early internal test, meaning the backlash was directed at something that was never going to ship.

Zach Yadegari's business plateaued at roughly $2 million per month using influencer marketing alone, and scaled further only after adding performance ads on Instagram and TikTok.
