There seems to be at least two tags on Stack Overflow referring to Finite-State machines:
finite-state-machine 178 questions tagged
Finite State Machine is a mathematical abstraction used as a behaviour model composed of a finite number of states, their transitions and functions to design digital logic or computer programs.
fsm 185 questions tagged
Acronym for Finite State Machine.
Furthermore, both seem to overlap at least somewhat with state.
I can't see how this is intentional, or benificial.
