A social media trend we don't 'like'

[Commentary] Be careful about the personal information and opinions you broadcast online, we are wisely and repeatedly told. Anyone from a prospective employer to an insurance company might be interested in details that you'll regret divulging someday. But employers cross a bright, hard line when they demand, as some do, that job applicants divulge their passwords to Facebook and other social media sites, or have them log on so the interviewer can scrutinize their likes and dislikes, their relationships, their photos, their friends' personal information. Several states have moved to pass laws outlawing this practice. In California, Sen. Leland Yee (D-San Francisco) has announced that he plans to introduce such legislation, and a U.S. senator from Connecticut is writing a similar bill at the federal level. Bans on these inquiries are a necessary response to an egregious intrusion.
