I believe that if you resort to using a ghost-tweeter to update your Twitter feed then you’re doing it wrong.
Why? Well mainly because I think social media is about customer (or audience) centricity. It is about placing the customer at the very heart of your business, and caring about what they have to say. And as such it has an impact on – and it reflects – organisational culture.
The brands that are doing social media right are very much focused on listening, sharing, communicating and responding. Outsourcing these tasks is myopic, and it can also be rather dangerous (especially if you fire the ghost-tweeter and fail to change the passwords to your social media accounts).
