Forbes: LinkedIn is becoming more and more important for hiring. The post notes a survey of staffing professionals, that is HR people and recruiters. 98.2% used some form of social media for recruiting in 2012. 97.3% used LinkedIn. Google+ came in 19.1%. In between were Facebook, 51.3%, and Twitter, 45.8%. The numbers for Twitter and Facebook are down from 2011 (60.2% and 51.5%, respectively). But watchout as Facebook rolls out the social graph search. Improved search may be able to find those individuals with the right mix of skills for your company.
