Def less people on here is a factor. That being said, something sensory and tangible about the UX makes me feel like im not doomscrolling. The only thing I can point to is Twitter has been relentlessly optimizing for DAU, session length, etc for years. That isnt FC's mission.
To be clear, I know that Farcaster does actually have a lot of product differentiators. I just don’t see them being discussed nearly as much as “who uses it” (or perhaps more accurately, who doesn’t).
