Facebook is responding to a call from top elected officials to crack down on Newtown school shooting conspiracy theorists. There are people who deny the terrible events in Connecticut in December and have been putting taunts and abuse on social media pages designed to help victims. Senators and a Congresswoman from Connecticut want Facebook to take the pages down; Facebook says no -- but points out that it has been dealing with the issue and is in constant contact with families affected by the tragedy. And Yahoo's new directive telling employees they can't work from home any more has generated debate...but is it a good idea?
