Facebook needs a warning label (Fox News)
The data now exist for Acting Surgeon General Rear Admiral Boris D. Lushniak, M.D., MPH to place a warning label on the Facebook Inc (NASDAQ:FB) homepage, not unlike that which exists on packages of tobacco cigarettes. Facebook has been linked, in numerous clinical trials both here and around the world, to feelings of intense envy, dissatisfaction with life, insomnia, major depression, disrupted friendships and feelings of isolation — especially in young people.

LinkedIn moves to protect teens (CBS Money Watch)
LinkedIn Corp (NYSE:LNKD), in a bid for continued growth, has decided to target high school students, much as Facebook Inc (NASDAQ:FB) did in its early years. Not only would the move open doors to the lucrative college recruiting market, but could get students accustomed to using the service. However, allowing users as young as 14 years old adds potentially thorny security and privacy issues. So LinkedIn Corp (NYSE:LNKD) is boosting the degree of protection available, including a way to block specific accounts, a feature the company has been criticized by some users for not previously offering.

Switch reader: Mark Zuckerberg should thank the guy who hacked his Facebook page (Washington Post)
It wouldn’t matter what we write here at The Switch if no one read it. That’s why we like to take a little time each weekend to feature some of our favorite comments from our dear readers.

The latest came from Yelp CEO Jeremy Stoppleman on the “Charlie Rose” show, AllThingsD reported.

LinkedIn Tells Noisiest Members To Hush, And A Ruckus Ensues (Forbes)
When Internet sites invite millions of members to post, it’s a safe bet that before long, shouting and head-banging will ensue. Facebook Inc (NASDAQ:FB) had a ruckus a while back, regarding photos uploaded by breast-feeding activists, or “lactivists.” Reddit struggled last year to deal with posts known as creepshots. (Don’t ask.) And now it’s LinkedIn’s turn. Yes,LinkedIn Corp (NYSE:LNKD), the site for 238 million people who take their jobs seriously. Joining LinkedIn and participating in the site’s specialty groups is widely seen as a great way to network. But LinkedIn’s huge, affluent, engaged audience can also look like a spammer’s paradise. And while everyone agrees that networking is good and spamming is bad, drawing the line between the two can be devilish.
