I think the key, however, is much simpler–if others call you an expert, you probably are. If you alone are calling yourself an expert, you’re probably not.

That being said–you definitely bring up some great points. And I would agree it’s the wrong move to “hire” someone to do “all your social media.” It should be an internally developed strategy first.
