"No one wants to talk to a logo. They want to speak with a person."Thomas Hoehn, Director, Interactive Marketing and Convergence Media, Kodak.
The takeaway here is:
When it comes to Social Marketing, Always Use A Real Person Behind Your Brand!
For example, Kodak's Chief Blogger’s Twitter profile features her picture above the Kodak logo. In the feed, she maintains a personal tone, but everything she says is with the knowledge that she is representing the company.
