How LinkedIn Got To It’s 100 Million Members?

On 22 March 2011 LinkedIn reached a major milestone: 100 million professionals worldwide. LinkedIn is now growing at over one million new members per week – the equivalent of a professional joining the social network at faster than one member per second.

To celebrate this milestone LinkedIn launched above website where people can tell and share their LinkedIn success stories.

What will be the future role of LinkedIn? Will it disintermediate the large headhunting firms and will companies do the hunt for new talent themselves via LinkedIn?

Is LinkedIn already a headache to the CMO’s of online job boards like Monster.com or will job boards move up the value chain themselves by becoming job matchmaking engines; not by offering the highest number of jobs, but matching candidates and companies even better, like a dating site?

Or will Career Networking on Facebook called BranchOut be the next social professional network?
