Robert,
Some schools have accounts that are controlled by others and they are typically for Lead Generation purposes which is a completely different objective than what career services has in mind. How can your career services department use social media to accomplish your objectives? First, identify your objectives and then ask yourself how social media simply plays a role...not THE role. Try to use social media not merely to disseminate information, but to drive the action you need. Think in marketing terms - what are the "conversions" you want to occur? Is this using a blog to build traffic (Audience), to engage audience, and to use that attention you've captured to sign up for events such as a webinar, a workshop, etc.? How can the audience built be used to help spread your message and get others involved? This is merely one simple example.
