We're doing a bit of research here at Center Theatre Group... and unfortunately... they're asking for the information TODAY. :( However, if you respond PAST today, I'm sure that information will still be helpful...
Our question is: Do you have a staff person who's primary job function is Social Media? Or do you have more than one person who's primary job function is Social Media? That's it. That's all we want to know.
My title is eCommunications Manager. Managing our permission-based email marketing, social media strategy, pay-per-click advertising, and some sections of web content are in my job description, along with other responsibliities.
While I do post frequently to our Facebook page, blog and Twitter feed - I also invite interested parties in departments across the center to participate. Our Public Information officer is responsible for posting "news" (anything he'd share with the media) to our social outlets. We also have people posting from our Patron Services (Volunteer and Access Services), Arts in Healing, Community Arts & Education, Green Team (our recycling initiative) Production, Membership, etc. These other departments have been asked to try and post something weekly, while the public information officer and I are posting multiple times daily.
One other thought on this topic:
I read somewhere recently that while social media was initially considered an area of specialization - requiring someone to occupy that specific role in an organization - as social media continues to gain legitimacy, organizations will realize it's not necessarily a position to be filled within an organization - but a skill set that all employees who interact with the public should have.
That rang true for me. We're shooting for Marketing/Communications to set the strategy for the institution - and multiple voices inside the organization to create and share the content. We're not there yet, but starting to move in that direction.
