FORBES - Feb 6 - A new survey by Bullhorn, a company that makes technology products for employers and recruiters, shows how powerfully LinkedIn still dominates the world of job search and recruitment. The results of a poll of 1,848 staffing professionals: 98.2% said they tapped some form of social media for recruiting in 2012. That’s up from 94% in 2011. 97.3% used LinkedIn as a recruiting tool in 2012. 19.1%, said they plan to use Google Plus for recruiting this year and 3.6% will use Pinterest. 17% made hires using Facebook in 2012. By contrast, only 13% said they made hires from their Twitter prospects. Graph Search is still in the beta phase, but once it’s fully up and running, it will allow recruiters and job seekers to search for a range of relevant terms. One other area Facebook has yet to penetrate: job listings. In Nov Facebook announced a new job search tool, Social Jobs App, a partnership with the U.S. Labor Department, the National Association of Colleges and Employers (NACE), DirectEmployers Association and the National Association of State Workforce Agencies (NASWA). There are also links from the app page to several job search sites like BranchOut and Monster.
