LinkedIn’s blog is reporting they now have over 50 million users worldwide. They say it took almost sixteen months for LinkedIn to reach its first million users. Their last million? Only took 12 days. This comes on the heels of even more good news, as Compete reported a 5.68% growth in traffic for LinkedIn during the month of September.

LinkedIn says that while 50% of its users are based in the US, 50% are international. An impressive stat that speaks highly to the power and success of LinkedIn. If you have somehow managed to stay away from LinkedIn to this point, now is as good of a time as any to jump on the wagon. Business is being done here, and soon every business man and woman will have their profile on LinkedIn.
