Few people are explicitly using local, but I think most people writing scripts broken up into functions still follow the design principle. Usign local just makes it harder to introduce bugs.

local makes variables available to function and its children, so it's really nice to have a variable that can be passed down from function A , but unavailable to function B, which may want to have variable with same name but different purpose. So that's good for defining the scope, and as Voo said - less bugs
