Linkedin the most successful business network is finally getting a business model - recruiting:

"Hiring managers, HR professionals and recruiters have flocked to LinkedIn Jobs because it enables them to leverage referrals from their existing professional relationships to prioritize applicants and to discover which of their own contacts know people who have had experience working with the candidate. 75 percent of all listings posted on LinkedIn Jobs so far have been for mid-to-senior levels, and 7 percent have been posted for senior executive positions."

Recruiting without the pain of having to screen hundreds of incoming profiles is a great benefit. I have no doubt Linkedin will get a foot in the marketplace dominated by monster.com in the US.
