Dive summary: 

• Over the last few days, LinkedIn has been sending out emails to users notifying them of their ranking in the top 1% or 5% of profile views in an effort to spark Facebook and Twitter mentions.
• Currently, there are 200 million LinkedIn users, and the top 5% includes 10 million profiles. 
• The risky marketing tactic has worked as many users have flocked to social media to discuss the emails, many of them using LinkedIn's prepackaged message — "Hurray! I have one of the top 5% most viewed @LinkedIn profiles for 2012."

From the article: 

"The congratulatory email contains a link to an even more celebratory page, complete with a ribbon, a stamp and a "personal" letter from the social network's senior vice president of products and user experience. It also encourages users to share their accomplishment with their friends with a text field that will export a message to their LinkedIn, Facebook and Twitter accounts."
