In an effort to engage its members, and provide additional value, LinkedIn kicked off its "Influencer" service in late 2012, featuring the likes of Bill Gates and Richard Branson. The idea was to give big-hitters like Gates and Branson, among others, a forum to impart their business and professional wisdom to the rest of us. Good idea, and it seems to have caught on, as the number of influencers has jumped to about 500. Now, LinkedIn has decided to open the floodgates, as it were, and let everyone in on its self-publishing content game. And while that sounds good, it also opens the possibility of LinkedIn becoming a little too Facebook-like.
