What do people think of the idea that Farcaster might be *too polite*? Like, people love to rail against the toxicity of twitter, but ultimately it's a PvP MMORPG and lots of people really enjoy the PvP - if not participating, then at least seeing some fireworks in the background...

This is a bit how Twitter started. 
It was benign, innocent and mostly polite. 
I think Farcaster’s issue right now is not having users. So, the early adopters are polite. Soon, it will be more crowded across the spectrum of behaviours.
