To answer that question, you really to have ask a different question: What’s the point of a social media job? Read the job description for any social media job listing and you’ll come across evangelist, community, marketing, engagement, and viral quite often. The jargon, though, can be summed up in two words: retention and growth.
Companies generally have one overarching goal: to increase profits. And anyone can tell you that keeping current customers (or users) and adding new ones is directly related to that single goal. These two things, keeping current users happy and adding new users, are the purposes of social media jobs.
And that’s why these jobs are here to stay.
