LinkedIn, 100M & Growing Strong

This morning, Donna Antoniadis (@DonnaAntoniadis) tweeted a link to an article about LinkedIn hitting 100 million members, and it got me to thinking about the size of the core social media networks. Many of us in the professional world have a LinkedIn profile, but because LinkedIn is rarely in the media, the perception is there that it’s a much smaller network. At 100 million users it’s still “significantly” smaller than Twitter (with ~175 million active accounts), but on the corporate blog LinkedIn CEO Jeff Weiner says they’re growing at a million new members every week, which is pretty significant for the site that puts the “networking” in social networking.
