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.
We have two people who are primarily in charge of our social media, but that's not all they're responsible for, and I wouldn't say it's either of their primary job functions at all, just that those two people are basically in charge of maintaining it for the institution.
Our set-up is similar to Heather's except we only have 2 people on our social media team. It is not the primary job responsibility for either of them (though probably one of their favorites!).
