Security starts at home: protecting kids from Internet peril is at the top of my digital agenda.

In a year that featured one of the most damaging natural disasters and one of the most controversial wars in U.S. history, it's hard to focus on systematic problems in this country. We desperately want to cling to the positives amid crushing national debt and pending environmental disaster. I understand the urge to tune out the negatives: It's just too depressing to face some of these realities. But we can't just ignore them and hope that they'll go away. We have to stay informed and ask ourselves what we can do to reverse these trends.
