With the common misnomer of using Warpcast and Farcaster interchangeably, I wonder how much it might have helped switching the -er.

Farcast: sounds like a noun, abstract

Warpcaster: sounds like a tool like ruler, calculator, etc.

father, husband, css golfer, ux engineer, silently defining variables as /sdv sdv.wtf

I think it's a good idea !
Farcaster is a concept of protocol, and warpcast is understood as a tool (=UI) that can access the society provided based on the protocol. Considering these uses, 'Farcast' and 'Warpcaster' might be more appropriate words~
