LinkedIn Reaches 100 Million Users

The professional online network LinkedIn, which has filed to go public, now has 100 million members, and is growing at a rate of one million new members per week.

To commemorate the occasion, the company made a fancy infographic (click to expand, or view the full-page version here) depicting some stats and trivia, such as 44 million of its users are based in the U.S., and its fastest-growing countries in 2010 were Brazil, Mexico, India and France.

NetworkEffect was planning to interview CEO Jeff Weiner for a keynote interview at the Web 2.0 Expo in San Francisco next week, but he had to pull out over concern about public disclosures in the lead-up to the IPO. (LinkedIn co-founder and Executive Chairman Reid Hoffman, who’s also a very active investor at Greylock Partners, is graciously stepping in.)

But LinkedIn hasn’t been entirely quiet lately; earlier this month the company launched a personalized news site called LinkedIn Today based on content shared by its members on its own site and through an extended integration with Twitter.
