Community Management is a very new role, due to social media being a popular means of contact a lot of work has to be done to moderate those pages and give users support.
I do a lot more out of my role too, but the community management role is very public facing, for example resolving issues through the forums, Facebook, Twitter, YouTube, Instagram, and all the other means of contacts. I even sign up to other peoples forums if I see an issue regarding OcUK to step in and resolve it.
But it is a means of keeping our online reputation strong, it is a hard job as everything is public and of course you have to be careful in what you say, but you need to be good at communications within the company, other companies you work with and the customer (you).
