LinkedIn, the "Anti-Facebook" professional social network, has recently reached a milestone 225 million users, and they made the announcement during their 10 year anniversary on Cinco de Mayo. To put the event in perspective, LinkedIn only had 4,500 members at the end of their first month in May 2003. To commemorate the occasion, they released a timeline of their past decade, which you can check out here. It's complete with pictures of their first iMac filled offices, with tons of papers tossed about the desks.
LinkedIn may be far off from catching up to Facebook's 1 billion users, but that doesn't seem to be part of their plan: sometimes, smaller is better.
