This morning, LinkedIn reached the milestone of 50 million members. CEO Jeff Weiner says that about 50% of the users are from the U.S. and the other half from the rest of the world. Weiner also noted an interesting fact about LinkedIn's growth.
When LinkedIn launched in 2003, it took 477 days -- almost a year and four months -- to reach our first million members. This last million took only 12 days.
Contributing to that momentum is India, which currently has the fastest growth of any country represented on LinkedIn. Eleven million members hail from Europe, and the tiny Netherlands has the highest growth per capita at 30%.
