Having watched the last season of Lost last night, I understand why Kinja is being changed again.
Ok so everyone remembers when they discovered the bunker, where they had to type in the code on the computer before the timer ran out or something "terrible would happen".
Well think of Kinja as that computer. Don't change it every few months and the world blows up. Or a random Baja Bug rolls over. Either or.
Just a theory.
