Struggling a bit with the value for this one. I don't mind it and people do search for Social Media Jobs. the .com is developed and is also ranked high in google.
I think it would need decent development to gain any real value and even then is going to require some work to gain a footing in search engines as these is reasonable competition for these keywords.
For any value you would need to develop it by connecting your site with an automatic feed of social media job openings from various job sites like CareerBuilder. Probably about a week or two process, but then you could easy make $ via flippa.
