Which platform-specific growth patterns have surprised you the most over the past year?

Okay, so which platform-specific growth patterns have surprised you the most over the past year? For me, it's gotta be how Bluesky just exploded out of nowhere after all the X drama—went from kinda niche to people actually talking about it daily in my feed. I remember back in late 2025 when a bunch of my friends started jumping ship from the old bird app, and suddenly Bluesky notifications were blowing up my phone with real conversations again, not just endless rage bait. Felt kinda refreshing, honestly, like going back to early Twitter vibes but without the chaos. Anyone else caught off guard by that one, or is it something else entirely for you guys—like maybe LinkedIn turning into this weird creator hangout?
