I'd bet renaming Warpcast to Farcaster would have a non-trivial impact on growth.

1. Improved onboarding conversion due to reduced confusion
2. The name is just better
3. One name instead of two names is gud

Putting the vibes based perspective (Farcaster is simply better) to the side for a moment.

It's probably hard to understate the impact on new user acquisition and general conversion rate for new users.

Any % improvements gained compounds greatly over time and impacts overall growth. And it comes for basically free.

I'm sympathetic to the developer neutrality point, but there is now a provably permissionless stack, the tech is credibly neutral. This wasn't the case a few years ago.

Also first and foremost the whole ecosystem dies if Farcaster/Warpcast does so it's important to bring in new users and grow—which is what is actually most important to developers.

Counterpoint: if a user can't search "farcaster" and find the warpcast app naturally through navigation/exploration then they may be a very low quality user.
