One of the things we'll remember 2012 for will be the raft of social media buzzwords and phrases that came our way. Influencer marketing, neutral point of view, content curation, content marketing, brand journalism... these are just five of the many. Should we give much credence to such words? Do we even know what they mean? And what influence should they have on PR and how we do things? A quick review of these and other topics will set the scene for a forward look into 2013 to shine a spotlight on what PRs should be paying attention to in the coming year - and how that attention can pay dividends in the leadership role PR ought to assume in the broad business landscape.
