I'm not a JS programmer, but I'd say that always using the function expressions (var a = function() {}) is bad. I understand that it's more useful when you intend to manage it as an object, or as part of a bigger object (the additional reasons your first link gives).

But about the hoisting problems... For me, the real problem is that you're declaring a function inside a function. Or using variables with the same name. That's a bad practice, it doesn't make sense. It should be avoided instead of using language constructs to work around it.
