Pressing the “Sympathize” Button?

Facebook, reportedly, is mulling the addition of a "sympathize" button to promote interaction with content that would be inappropriate to "like." That's part of a broader trend toward the categorization of content according to the moods and emotions it triggers, Brian Feldman writes in an article on The Wire. Of course, when you get right down to it, this means, basically, that people aren’t sociopaths and can recognize basic social cues. What do your kids think of the “Like” button? Do they think it works? Should people make a bigger effort to reply to postings than just pressing a single button?
